PAO is comprehensive package for mobile-computing users of FreeBSD.
PAO contains FreeBSD PC-card drivers, enhancements of FreeBSD APM
driver, and other miscellaneous utilities and daemons.  PAO is based
on Andrew McRae's early work on FreeBSD PCMCIA driver, and Tatsumi
Hosokawa's FreeBSD APM driver, and it is now developed and managed by
BSD-nomads team and Nate Williams.

--------------------------------------------------------------------------

1.	General Information

* What does PAO stand for?

	PAO stands for nomads :-).

2.	Supported Hardware

* What cards does PAO supports?

	Please read SUPPORTED.CARDS in the package.

* What laptops does PAO supports?

	APM driver of PAO supports APM BIOS 1.0 and APM BIOS 1.1.  APM
	BIOS sometimes has many serious bugs.  We're trying to cope
	with these bugs, but we gave up supporting some broken APM
	BIOS'es.  Some laptop vendors announced that they have updated
	their BIOS'es 'for Windows 95'.  It probably means that 'they
	fixed bugs on APM protected mode interface.'  So, if the
	vendor of your laptop has announced newer BIOS'es, please
	update it to the latest one before installing PAO.

	PC-card driver of PAO supports following PC-card controllers.

		Intel i82365SL (and compatibles)
		Cirrus Logic PD-6710
		Cirrus Logic PD-6720
		Cirrus Logic PD-6722
		Cirrus Logic PD-6729 (PCI-PCMCIA bridge)
		IBM PCIC (on some ThinkPads)
		IBM KING
		Vadem 468
		Vadem 469
		Ricoh RF5C396
		VLSI 82C146

	PAO does not support following PC-card controllers.  If you
	have laptops with these controller, please write drivers of
	these controllers for PAO :-).

		Databook TCIC (on some ancient laptops)
		Any PCI-CardBus Bridges
		ZV-port controller

	Some PCI-CardBus bridges can be used in i82365-compatible
	mode.  For example, Texas Instrument's CardBus bridge PCI-1130
	works under FreeBSD in i82365-compatible mode.


3.	APM BIOS

* What does APM stand for?

	Microsoft and Intel's "Advanced Power Management".  Please
	read http://www.intel.com/IAL/powermgm/powermgm.htm for
	details.

* This kernel hangs up when it uses APM BIOS.  Why?

	Some implementations of protected mode APM BIOS has serious
	bugs.  At first, confirm that your laptop has the latest BIOS.
	These days, BIOS'es of many laptops has been updated to fix
	these bugs of protected mode APM BIOS because Windows 95 uses
	it.  If the BIOS is not latest one, update it soon.  Even if
	the BIOS is the latest one, you can "cope with" these problems
	by modifying the kernel source.  If your problem is
	solved, please send us a report about your solution (and of
	course your environment).  If you're not hacker, boot the
	kernel with "kernel -c" and type simply "disable apm0" :-).

	APM driver of PAO can be configured to cope with some
	incompatiblity problem of APM BIOSes from UserConfig.  apm0
	device has one "flags" mask for this purpose (the problem
	corrresponded to 0x01 -- APM data segement value -- has been
	fundamentally solved in current version).

	0x02: Some APM BIOS that is called APM 1.1 has incomplete
	implementation of APM 1.1 specification.  This flags forces
	APM dirver to drive APM BIOS in 1.0-compatibilty mode
	regardress of the version number APM BIOS reports.

* I can't use apm(8) and zzz(8).  Why?

	apm(8) (zzz(8) is hard-linked shortcut of `apm -z') is APM
	BIOS utility.  It uses APM BIOS device file /dev/apm to
	controll APM.  The permission bit of /dev/apm is set to:

	crw-rw----  1 root  operator   39,   0 Jun 15 15:58 /dev/apm

	It means /dev/apm is only accessed by users registerd as
	`operator' group or super user.  If you want to use apm(8)
	(and zzz(8)) and you don't want to use su(1) for this purpose,
	register yourself as `operator' group by editing /etc/group.

* I can't use xbatt(1).  Why?

	xbatt(1) is X client that display battery and AC line status
	on X.  xbatt(1) in 2.1.5-RELEASE ports/packages collection
	does not work on current PAO system.  This version of xbatt(1)
	uses APM device file /dev/apm0.  The name of APM device is
	currently /dev/apm (not apm0).  Ad-hoc solution is:

		 # cd /dev
		 # ln -s apm apm0 

* The system clock loses time when the machine is sleeping, and never
  catch up current time when the machine comes back from suspended
  mode.  Why?

	Maybe you have forgotten to set YES to variable apm_enable in
	/etc/sysconfig :-).

* My laptop sometimes hangs when ths system is resumed from suspended
  mode.  Why?

	Of course there are some reasons.  For example, I experienced
	following problems.

	o APM BIOS itself is instable :-).

	o Unsupported internal sound card causes interrupt on PC-card
	  controller when the system is resumed.  Current code
	  determins IRQ of PC-card controller based on IRQ allocation
	  table in FreeBSD kernel.  Therefore, unsupported sound card
	  can have the same IRQ which is allocated for PC-card
	  controller.  If you have such machine, you can avoid this
	  problem in following ways.

		- Don't give up and try again to use this sound card
		  by FreeBSD :-).

		- Disable sound card from BIOS setup.  But if you do
		  it, you can't use the sound card from Windows.

		- Use PCIC_IRQ option in config file.  See PAO config
		  file for details.

	o Even if your sound card is supported by FreeBSD, you have to
	  configure sound driver or disable sound card from BIOS setup
	  because of the same reasons.  Don't leave the sound card
	  unused.

4.	PC-card

* Kernel boot message says that my card is not probed.  Why?

	No problem.  Kernel can't find your card without pccardd
	daemon, and card database stored in /etc/pccard.conf.
	PC-cards are not probed at bootstrap.  It will found and
	registerd by pccardd later.

4.1.	PC-card Controller

* Removing a card freezes the machine.  How can I ward off this
  trouble.

	On current version, hot removal of some particular serial
	cards (or on paticular machines?) is still unstable.  Using 'xpccard'
	(in utils/ subdirectory of this package) or 'power' subcommand
	of 'pccardc', and hybernate the card first, you would remove
	these cards safely.

* I installed PAO on my machine, but the machine frequently reports
  that card is inserted or removed even though no cards are attatched
  to the machine.   Why?

	Maybe your machine has built-in devices which does not probed
	and attatched by FreeBSD (for example, unsupported built-in
	sound card).  If you can disable such devices from BIOS setup
	screen, please disable it and test it again.

	If the problem does not happen again, it's IRQ confilict
	between PC-card controller and built-in unsupported devices
	that caused the trouble.

	We can explicitly specify the PC-card controller's IRQ with
	PCIC_IRQ option of config file, like,

	options "PCIC_IRQ=7"

	Please note that:

	1. If you can disable printer parallel port from BIOS setup,
	   you can make IRQ 7 be free.

	2. If you can disable COM2 from BIOS setup, you can make IRQ 3
	   be free.  Generally, you can't use serial mouse if you
	   disable COM2.

	3. If you can disable COM1 from BIOS setup, you can make IRQ 4
	   be free.

	4. If your machine has no PS/2 mouse or PS/2-compatible
	   trackball/trackpad, you can use IRQ 12 freely.

* I installed PAO on my machine, but it does not report the
  insertion/removal of cards.  Why?

	Maybe the same reason as last question.  Use PCIC_IRQ option.

* When I insert cards, system says only "CIS code read: Cannot
  allocate memory".  Why?

	Maybe you forgot to enable "pccard_enable" parameter in
	/etc/sysconfig.

* My laptop says "Slot ?, unfielded interrupt (?)".  Why?

	No problem.  Don't mind :-).

* My laptop uses I/O address 0x240 for another device, but I can't
  change I/O address even though I modified corresponding device
  declarations in config file.  How can I change I/O ports?

	Value of I/O address in config file is "dummy".  If the card
	is allocated I/O ports from I/O pool, please modify following
	line (corresponding to I/O pool definition) of
	/etc/pccard.conf.

	io	0x240-0x2e0 0x300-0x360

	For example, modify it as

	io	0x300-0x360

	it won't use 0x240-0x2e0.  If the card is allocated I/O ports
	according to their CIS tupples, change config index number
	(see "config" declaration in /etc/pccard.conf) to other
	indices.  For example, Ratoc REX-5588 Ethernet card has
	following tupples (dumped by "pccardc dumpcis").

--------------------------------------------------------------------------
Tuple #16, code = 0x1b (Configuration entry), length = 8
    000:  08 08 ea 60 00 01 1f ff
	Config index = 0x8
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x100 block length = 0x20
Tuple #17, code = 0x1b (Configuration entry), length = 8
    000:  09 08 ea 60 20 01 1f ff
	Config index = 0x9
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x120 block length = 0x20
Tuple #18, code = 0x1b (Configuration entry), length = 8
    000:  0a 08 ea 60 40 01 1f ff
	Config index = 0xa
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x140 block length = 0x20
Tuple #19, code = 0x1b (Configuration entry), length = 8
    000:  0b 08 ea 60 60 01 1f ff
	Config index = 0xb
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x160 block length = 0x20
Tuple #20, code = 0x1b (Configuration entry), length = 8
    000:  0c 08 ea 60 80 01 1f ff
	Config index = 0xc
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x180 block length = 0x20

		    ..........repeats............

Tuple #39, code = 0x1b (Configuration entry), length = 8
    000:  1f 08 ea 60 e0 03 1f ff
	Config index = 0x1f
	Card decodes 10 address lines, full 8/16 Bit I/O
		I/O address # 1: block start = 0x3e0 block length = 0x20
--------------------------------------------------------------------------

	This card specifies I/O address explicitly.  For example, if
	you use config index 0xc, I/O address 0x180 is used.  If you
	want to use 0x3e0 as I/O address, you must specify 0x1f as
	config index.  I'm planning to extend pccardd to treat such
	cards automatically, but you must specify config index
	manually with current version of our PC-card package.

* My laptop uses IRQ 10 for another device, but I can't change IRQ
  even though I modified correspondig "device" declaration in config
  file.  How can I change IRQ?

	If the corresponding entries in /etc/pccard.conf specifies IRQ
	explicitly, modify that value.  For example,

	card "PCMCIA LAN MBH10304  ES" "  01"
		config	0x1a "fe0" 5
		ether	0x32c 00:c0:d0

	this entry uses IRQ 5 explicitly.  If you want to use IRQ 7
	for this card, modify "config" declaration as

		config	0x1a "fe0" 7

	If the entry uses dynamic IRQ allocation ("any" for IRQ), the
	IRQ is allocated from free IRQ pool.  Free IRQ pool is defined
	at "irq" declaration of /etc/pccard.conf.  By default, 

	irq	10 11

	is defined as the free IRQ pool.  If your machine uses IRQ 10
	or IRQ 11 for other devices, modify this list.  You must
	Declare free IRQs more than the number of slots.  (So, if your
	machine has four PC-card slots, you must prepare more than
	four free IRQs!)


4.2.	Ethernet

* How can I plug two network cards into a laptop and use it as a
  gateway?

	If you want to use two network cards correspond to different
	drivers respectively (for example, Ethernet and Modem, or IBM
	Ethernet card and 3Com Ethernet card), no special
	configuration is needed.

	If you want to use two same cards (for example, two IBMp
	Ethernet cards), or two different cards correspond to same
	drivers (for example, IBM Ethernet card and Accton Ethernet
	card), you must modify /etc/pccard.conf.

	(example 1) two IBM PCMCIA Ethernet cards:

	At first, you must configure "ed0" and "ed1" both.  By
	default, PAO configuration file defines "ed1" as "disabled"
	state.  So, if you have not modified PAO, type simply "enable
	ed1" from "kernel -c" prompt.  Otherwise, edit config file,
	enable "ed1", rebuild the kernel, and install it.

	Next, you must define "config" line in /etc/pccard.conf
	correspond to second IBM card.  A "card" definition can have
	more than two "config" lines.  For example, if you configure
	IBM cards as

	card "IBM Corp\." "Ethernet"
		config	default "ed0" any
		config	default "ed1" any
		ether	0xff0 08:00:5a 00:04:ac
		insert	echo IBM PCMCIA Ethernet inserted
		insert	/etc/pccard_ether $device
		remove	echo IBM PCMCIA Ethernet removed
		remove	/etc/pccard_ether_remove $device

	you can use second IBM cards.  Resources are allocated without
	confilicts automatically.  If you want to use the cards that
	specifies config index and IRQ explicitly (i.e. not by
	"default" or "any" keyword), you must manually choose other
	indices or IRQ that does not conflict with each other.

	(example 2) IBM Ethernet card and Accton Ethernet card

	You must configure one card as "ed0" and the other as "ed1".
	Following example uses IBM card as "ed0" and Accton card as
	"ed1".

	card "IBM Corp\." "Ethernet"
		config	default "ed0" any
		ether	0xff0 08:00:5a 00:04:ac
		insert	echo IBM PCMCIA Ethernet inserted
		insert	/etc/pccard_ether $device
		remove	echo IBM PCMCIA Ethernet removed
		remove	/etc/pccard_ether_remove $device

	card "ACCTON" "EN2212"
		config	default "ed1" any 0x30
		ether	0xff0 00:00:e8
		insert	echo Accton EN2212 inserted
		insert	/etc/pccard_ether $device
		remove	echo Accton EN2212 removed
		remove	/etc/pccard_ether_remove $device

	If the card uses explicit config index specification, same
	problem as "example 1" may happen.

	We're trying to solve the problem related to explicit config
	index specification.  Please wait for the future releases.

* Failed to use NE-2000 compatible Ethernet cards while the entries of
  /etc/pccard.conf seems to be correct.  Why?

	Some NE-2000 compatible Ethernet card has weired CIS tupples
	about the description of shared memory address (Accton
	EN-2212, etc.). Adding flags 0x10 at the corresponding entry
	of /etc/pccard.conf.  It diables the use of shared memory and
	force the driver to work in program I/O mode.

     card "PCMCIA" "UE2212"
	     config  default "ed0" any 0x10
	     ether   0xff0 00:00:e8

* I can't use WaveLAN at all.  Why?

	WaveLAN driver is provided for 2.2-SNAP only.  If you're using
	2.1.5-RELEASE, you can't use WaveLAN.  Even if you're using
	2.2-SNAP, you must specify -DWAVELAN as the argument of cc
	when you compile pccardd.  Read Makefile of pccardd for
	details.

* My WaveLAN card is probed correctly, but I can't use it.

	You must initialize WaveLAN card from DOS utilities before
	using it.  Especially, you must set the same NetID on all
	WaveLAN cards (and of course WavePoint) you want to
	communicate with.  And, please note that roaming protocol is
	not supported yet.

	PAO package before PAO-960911 had a problem with Japanese
	version of WaveLAN.  Japanese version uses 2.4GHz band instead
	of 915MHz band that US version uses.  This bug is fixed on the
	current version.

* How can I use Xircom's card?

	Don't ask me.  Ask Xircom instead :-).

4.3.	FAX/Modem

* Kernel says that my modem is attached as "sio2", but there are no
  /dev/sio2.  Why?

	Use /dev/ttyd2 or /dev/cuaa2 instead (same as desktops).

* Failed to probe (or probed correctly, but behaves unstable) PCMCIA
  FAX/Modem cards (or other serial cards).  Why?

	Read "function serial" definition in /etc/pccard.conf and try
	alternative definitions.


4.4.	Flash ATA/ATA HDD/ATAPI CD-ROM

* How to mount Flash ATA disk?

	I think that most popular purpose of Flash ATA disk for
	FreeBSD laptop user, is to share files between FreeBSD machine
	and MS-DOS palmtops like HP-200LX.  For example, MS-DOS
	filesystem of HP-200LX is usually placed at the first fdisk
	partition of Flash ATA disk. So, if you mount this partision
	(this example assumes Flash ATA disk controller was attatched
	as "wdc1" and Flash ATA disk is attached as "wd1", as defined
	in PAO config file and pccard.conf.sample), type

		# mount -t msdos /dev/wd1s1 /mnt

	If you want to do it more easily, make directory /flash for
	this purpose, and add a line like

	/dev/wd1s1         /flash        msdos   rw,noauto 0 0

	into your /etc/fstab (don't forget to add "noauto" option).
	You can mount this partition by simply typing

		# mount /flash

	Don't forget to umount filesystem before removing the cards.

	If you have digital still cameras that support Flash ATA
	cards, you can read image data captured by these cameras.
	Especially, if the camera supports MS-DOS formatted Flash ATA
	disks or ATA HDDs, you can view captured images, as long as
	the image file format is supported by the graphic viewer on
	FreeBSD.  For example Ricoh DC-2 writes *.j6i and *.j6s files
	on MS-DOS root directory in the first fdisk slice of Flash ATA
	cards.  The manual says that *.j6i format is "based on JPEG
	compression", but, in fact, if you truncate the first 172
	bytes from *.j6i format, the remainder is standard JPEG
	format.  For example, when the name of j6i file is
	"/flash/r010001.j6i", you can view this image with xv by,

		% dd if=/flash/r010001.j6i of=foo.jpg skip=1 bs=172
		% xv foo.jpg

	Please note that you must adjust aspect ratio.  You can do it
	with cjpeg/djpeg and netpbm package.

* How to mount ATAPI CD-ROM?

	Same as desktops.

		# mount -t cd9660 /dev/wcd0c /cdrom

	If you add this line

	/dev/wcd0c         /cdrom          cd9660  rw,noauto 0 0

	to /etc/fstab, you can mount SCSI CD-ROM by simply typing

		# mount /cdrom

	Don't forget to umount filesystem before removing the cards.

4.5.	SCSI

* How to mount SCSI CD-ROM?

	Same as desktops.

		# mount -t cd9660 /dev/cd0a /cdrom

	If you add this line

	/dev/cd0a         /cdrom          cd9660  rw,noauto 0 0

	to /etc/fstab, you can mount SCSI CD-ROM by simply typing

		# mount /cdrom

	Don't forget to umount filesystem before removing the cards.

* How to mount SCSI HDD?

	Same as desktops :-).

* I want to use portable CD-ROM drive, but it doesn't work.  Why?

	Some portable CD-ROM drives uses non-standard device driver on
	Windows.  I think these non-standard drivers controls the
	power for the drives.  Some of these drives can't be probed
	when the SCSI PC-card is plugged into the host.  I heard that
	this problem doesn't happen if you turn on the power of CD-ROM
	drive manually just when you plug the card into the host.

4.6.	Video Capture

* How/where can I get IBM Smart Capture Card?

	I heard that this card is available at Japan (and Europe?) 
	only.   Ask IBM in your country for details.

* Are there any other applications than xscc for IBM Smart Capture
  Card?

	xfscc	- SCC client with xforms interface
	sccat	- snapshot captureing tool
	NV	- video conference application
	VIC	- video conference application

	Please read "SCC on FreeBSD/Linux" page for details.  The URL
	of this page is
	"http://www.mickey.ai.kyutech.ac.jp/~ohashi/scc/index.html".

4.7.	Multifunction Card

* Are multifunction cards supported by PAO?

	No.  But now I'm modifying pccardd and kernel to use
	multifunction card (I'm using Megahertz XJEM1144 Ethernet /
	Modem card as testbed).

5.	System Installation

* How can I install FreeBSD via PC-cards PAO supports.

	Now I'm also involved in multilingual boot.flp project
	(currently supports English, Japanese, and Chinese).  This
	boot.flp also supports PAO, and you can install PAO
	automatically by typing only

		# cd /stand/PAO
		# ./PAOsetup

	if you've installed FreeBSD with this floppy.  This floppy is

* How to configure the variables in /etc/sysconfig?

	1. apm_enable

		If this variable set to YES, you can use /dev/apm
		application interface, and kernel can handle APM
		events (default: NO).

	2. pccard_enable

		If this variable set to YES, PC-card manager daemon
		starts at bootstrap (default: NO).

	3. pccard_mem

		If you want to use scratch memory for PCIC other than
		DEFAULT (0xd0000), set this variable explicitly
		(default: DEFAULT).

	4. pccard_beep

		If pccard_beep is set to 0, insertion and removal of
		PC-cards is set to silent mode.  If it is set to 1 or
		2, the machine beep's when the card is inserted or
		removed.  1 and 2 correspond to simple beep mode and
		melody mode respectively (default: 2).

	5. pccard_ether

		List all ethernet interfaces configured in your
		kernel.  For example, if you use PAO as the config
		file, appropriate value of this variable is
			    pccard_ether="ed0 ep0 fe0 sn0"
		(default: NO).

	6. ifconfig_"interface name"

		Set arguments for ifconfig corresponding to all
		interfaces listed in "pccard_ether".  If this variable
		set to "DHCP", DHCP (Dynamic Host Configuration
		Protocol) clients is automatically executed for
		correspoinding interface.  If you want to use "DHCP",
		you must install WIDE-DHCP package in ports/packages
		collection and configure BPF (Berkeley Packet Filter)
		in your kernel (PAO config file has this definition).
		And, don't forget to MAKEDEV bpf? devices.

		(example 1)
			pccard_ether="ed0 ep0 fe0 sn0"
			ifconfig_common="10.0.0.1 netmask 0xffffff00"
			ifconfig_ed0=$ifconfig_common
			ifconfig_ep0=$ifconfig_common
			ifconfig_fe0=$ifconfig_common
			ifconfig_sn0=$ifconfig_common

		(example 2)
			pccard_ether="ed0 nep0 fe0 sn0"
			ifconfig_common="DHCP"
			ifconfig_ed0=$ifconfig_common
			ifconfig_ep0=$ifconfig_common
			ifconfig_fe0=$ifconfig_common
			ifconfig_sn0=$ifconfig_common

	7. defaultrouter

		If you set this variable, default router is
		automatically registered into the routing table when
		you inserted the card, and automatically deleted from
		routing table when you removed the card.  This
		variable is ignored when the ifconfig parameter of
		corresponding interface is set to "DHCP". (default:
		NO)

* I'm using IBM ThinkPad 3xx series and I want to install FreeBSD, but
  FreeBSD keyboard driver can't handle keyboard correctly.  So I can't
  install FreeBSD.  Why?

	That's because these machines use XT-compatible keyboards.
	The old version of PAO has a patch to configure this feature
	from UserConfig, but this patch has been incorporated to
	FreeBSD since 2.2-ALPHA. Boot from installation floppy with
	"kernel -c" option and type

		flags sc0 0x10

	at UserConfig prompt.  This enables XT-compatible keyboard
	mode of syscons driver.

* "Gated" does not work on PAO system.  Why?

	That's because gated does not support "dynamic interface
	emergence" that PAO provides.

* I tried to change IRQ and I/O address of PCMCIA cards by using
  "kernel -c", but it has no effect.  Why?

	"kernel -c" and arguments of "device" and "controller"
	definitions in config file (except the definitions of
	"xxxintr") have no effect to PCMCIA cards.  If you want to
	modify these parameters, edit /etc/pccard.conf.
