So has anyone gotten an ATI video card to work without the emulation BIOS?

Enable v.s. Enabled
by Li-Ta Lo
Hi,
I changed the device:enable and chip_device_path::enable to
device:enabled and chip_device_path::enabled because they
are acutally verbs describe the status of the devices.
I also change all the affected code I can find, there should
be no problems except you have to re-run the config tool.

LinuxBIOS Video?
by Langlois Evan
Hi,
If video isn't supported on a particular board, does this mean that video
won't work at all? I could live with no video until after the Linux
kernel initialized things, but I'm guessing that the card won't even be
listed in the device table.
Could someone explain this to me? Does this apply only to on-board video,
or all add-on cards. Am I right in guessing that no add-on video cards
are supported? Would it be possible to go into 16 bit mode temporarily
to jump into the video ROM and initialize the card?
Basically, I want a fast desktop (K8 maybe, the bus speeds seem to make it
worth it) without a PC BIOS (I only use Linux, usually Gentoo). It looks
like LinuxBIOS is mainly for headless clusters. The "Status" file on the
web site looks painfully outdated, and the FAQ really needs some updates,
and the mainboard directory in the source wasn't quite specific about what
was supported either.
I haven't gotten anything from this list in awhile, so please copy me
directly as it would seem mail from the list isn't getting to me for some
reason (possibly a problem at my end).
Thanks,
Evan Langlois

1. S2875 support is in the CVS tree already.
2. ATI randon --- At this time, you may not get the output from very
beginning.
3. boot sata --- good question, I will try that. Maybe need to add some code
in filo.

Best choice for I/O hub for AMD Opteron
by Craig C Forney
Looking for advice and counsel regarding LinuxBIOS support for I/O hub
alternatives ...
We've just completed a very dense cPCI dual Opteron design with an AMD
8111 as the I/O hub, no superIO, no 8131, no 8151, with 8GB SDRAM.
LinuxBIOS seems to work fine, although the lack of legacy support for
serial I/O was problematic (we ended up simulating a serial port).
Thanks for everyone's support on helping us with early issues getting up
to speed with LinuxBIOS.
For our next generation, we would like to use a better supported and
more integrated I/O hub than the 8111 (USB 2.0 doesn't work on the 8111,
to start with). The nVidia nForce 3-2506B and the VIA K8T800 Pro seem
to have a lot of potential, but I'm concerned about support for these
from the manufacturers as far as LinuxBIOS is concerned. We don't mind
helping with debug on any new code required, but we don't want to even
start unless we have some confidence that there will be some level of
support and effort behind our choice (and that we are not alone).
Are there any opinions out there about these (or other) candidates
related to LinuxBIOS?
Any comments appreciated.
Regards,
Craig Forney

答复: LinuxBIOS Video?
by YhLu
To make the onboard ati rage xl framebuffer work under linux, you need patch
for 2.4.22 and 2.6.5. the original ati framebuffer even not work under
normal bios.
In SUN sparc openboot and PowerPC MAC, I guess they are using framebuffer to
show text for booting....---> they have limited display card. How about us,
only support ati rage xl now.
I wonder if we can enable framebuffer for add on display card so we can get
output from crt via btext console.

It's a bit sketchy at the time. Right now we can use ATi embedded devices
(Rage XL) pretty well, some older stuff like on the SiS630, and EPIA
whatever. But for newer stuff like GeForce cards, we have had to toggle
some IORRs and stuff and run the VGABIOS after Linux is booted. From here,
framebuffering can be used for console display and X can run fully
accelerated in AGP8x with fast writes and side band addressing. This has
only been tested by us on the Tyan S2885.

SMBus and HW monitor
by Li-Ta Lo
Ron,
You copied some smbus and hw monitor code from hdama
to e325. Are they correct on this board ? Is the
hardware the same across those k8 boards ? Should we
move it to some shared directory ?

Canonical order of dev_find_device()
by Li-Ta Lo
Eric,
Is there any order for dev_find_device() ? In linux
kernel, if there are two devices have the same vendor
and device ID, the one with lower BUSDEVFN will be
returned first and when the function is called again
with the first returned device structure as parameter,
the one with higher BUSDEVFN will be returned. Is it
the same for LinuxBIOS ?
There are some hard coded BUS_DEV_FNs for 8111/8131
bridges in mptable.c for all mainboards. Can we just
search for these bridges by ID instead of the hardcoded
values ?

Boot PC from Compact Flash
by manisha s
Hi All,
I m new to this mailing list.
I want to boot my laptop from 128Mb Compact Flash(CF)
Card.
On laptop i have already RedHat 9 with kernel version
2.4.22.
I downloaded the pebble linux distribution and
successsfully downloaded (wrote) this on to the CF.
The CF card is available as /dev/sdb on the linux
through CF card reader/writer.
I changed /etc/grub.conf file so as to include the CF
card
title Pebble(Pebble)
root (hd0,1)
kernel /mnt/pebble/boot/vmlinuz-2.4.22-pebble
ro root=/dev/sdb1
title Red Hat Linux (2.4.22)
root (hd0,1)
kernel /boot/vmlinuz-2.4.22 ro root=/dev/hda2
initrd /boot/initrd-2.4.22.img
should i copy the vmlinuz-2.4.22-pebble to /boot
directory?
should i change other than this?
plz shed some light on this issue?
Thanks in advance
