FWIW the LinuxBIOS project started with the FreeBIOS code.  FreeBIOS was
apparently code from 'Net Insight AB' written to boot NetBSD on the STPC
Consumer.  By now the LinuxBIOS project has purged most of the original
code, but presumably someone could start another project based on the
original freebios code.

I have a BIOS implementation that I wrote on contract to Dynarc AB, and
which is released under a BSD license. It only works on ASUS P5A
motherboards /w K6 CPU, but should be trivial to port to other boards
and other CPUs.

The source, if anyone is interested, can be found at
ftp://bakfull.campus.luth.se/bios/nbsd-bios.tar.gz

Interesting! You should announce this more widely...

Yes, probably, it is just one of all projects that I have had around
that should be distributed.

I think I wrote something about it on some mailing list back in 2001,
but never got any reasonable response.

memory disk, evbarm - lubbock

I am trying to create a memory disk within the kernel
for the evbarm port to the LUBBOCK eval board.
(LUBBOCK is Intel's DBPXA250 eval board for the XScale CPU). 
Ultimately I want to put the root filesystem on the memory disk,
but have got that far yet because I cant make the memory
disk large enough.

I can compile a kernel with up to 4096K space set aside
for the memory disk, but when I try to make it larger I
get a kernel panic. 
Oddly enough, when I make it much much larger (16384K or more)
the kernel boots ok, but /sbin/init seg faults.

Is there a limit on the size of a memory disk?
I'd like to make one about 30MB, is that a silly thing to try???

For the record, my kernel config has:
	options 		MEMORY_DISK_HOOKS			#
boottime setup of ramdisk
	options		MEMORY_DISK_SERVER=0   		# no userspace
memory disk support
	#options 		MEMORY_DISK_IS_ROOT		# use memory
disk as root (disabled for now)
	options           MEMORY_DISK_ROOT_SIZE=8192 	# (md0=4096K)

	# disk/mass storage pseudo-devices
	pseudo-device	md		1			# memory
disk device (ramdisk)

My config file has other options that no longer seem to have any effect,

Starting Point

I am looking for a PDA to act as a remote terminal. I was wondering which platforms would be a good starting
point. I'm looking for a device with a long battery life and a touch screen. NetBSD compatability is
desired, but not required.

Thanks for the info,

I run NetBSD on a Jornada 720 and use it as a serial console terminal, and data
logger for my GPS.

When you say remote terminal, do you mean wireless? I think you can get
vt100 emulators for palm os , so if you just want a serial console that'd
do you...

I've got a mobilepro 800 I use as a wifi xterm , which has a 9" screen and
a full keyboard, but with the cf card and the wirless nic i didn't get
much change from 250 quid after shopping on ebay.

a palm would be about 50-60 UKP.

Psion 5MX.  Small enough to fit in a moon bag (but a bit large to fit
in a pocket), keyboard that some people claim is good enough for touch
typing, greyscale LCD touch screen with backlight and good contrast,
vt100 emulator that supports 80 colums by 25 rows (in a tiny font),
works for several tens of hours on two AA batteries.  Sorry, no NetBSD,
and I don't know what progress has been made on the Linux port.

Actually, there is some work ongoing on a Psion Windermere port:
