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

Enable v.s. Enabled
by Li-Ta Lo April 30, 2004

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. Ollie

LinuxBIOS Video?
by Langlois Evan April 29, 2004

April 29, 2004

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 The "Status" file on the web site looks painfully outdated, and the FAQ really needs some updates, and the mainboard directory in the source wasn't quite specific about what was supported either.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. Regards YH

Best choice for I/O hub for AMD Opteron
by Craig C Forney April 28, 2004

April 28, 2004

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 Opus Innovations LLC Cupertino, CA

答复: LinuxBIOS Video?

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. YH -----邮件原件----- 发件人: Hendricks David W.

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 April 28, 2004

April 28, 2004

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 ? Ollie

Canonical order of dev_find_device()
by Li-Ta Lo April 28, 2004

April 28, 2004

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 ? Ollie

Boot PC from Compact Flash
by manisha s April 28, 2004

April 28, 2004

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?
