[LinuxBIOS] New version of ROM posting app
by Jon Smirl 14 Apr '05

14 Apr '05

I put two new posting apps, a vm86 version and emu86 version out on: bk://mesa3d.bkbits.net/rom Get klibc from: http://kernel.org/pub/linux/libs/klibc/ Install it somewhere and build it. You need to make a link to the kernel source in the top level klibc directory. In this directory make a link from the klibc-xxx directory to klibc. Both projects will then build. v86bios uses vm86 to run the rom post uses emu86 Use an environment variable to pick the card to be acted on: export DEVPATH=/bus/pci/devices/0000:01:00.0 vm86 is 20K non-debug emu86 is 40K non-debug Currently they don't use Ben's VGA arbiter which isn't ready yet. When finished these app will automatically be triggered on driver load as part of the hotplug process. The source to vm86 is from the linux BIOS project where is has been worked on to make it substantially smaller. I like to keep everyone on the same source code base if possible. Once we get these cleaned up and working I'm hoping to get them added to the klibc project. Once in klibc, klibc is schedule to go into the kernel sooner or later. They are both partially working but fail part way through the posting process. I've been playing with them a couple of days and I can't figure out why they are failing. They are both failing for different reasons. Can anyone help? -- Jon Smirl jonsmirl(a)gmail.com

RE: [LinuxBIOS] [PATCH 2/2] amd8111_nic: Set MAC address in linux bios
by YhLu 31 Mar '05

31 Mar '05

Should be in BIOS.because different MB use different MAC assigned in Factory. But in MB design, it should use another SEEPROM to store that. So the BIOS or NIC get it.

[LinuxBIOS] Mount linux elf image for netboot as loop device
by Tony Cheng 31 Mar '05

31 Mar '05

I used mkelfImage to combined Linux Kernel 2.4.20 and initrd into elf image for netboot. then I try to use "mount -o loop my_elfImage" to mount this image as a loop device. I get a error message like this: #mount: you must specify the filesystem type I have specified the my_elfImage in /etc/fstab as this: (I add a line in fstab because mount ask me to do that) /root/loop/my_elfImage /root/loop/tl auto noauto,owner,kudzu 0 0 I changed the file type from auto to ext3 and etc. but nothing work for me. Could anybody kindly help me on this? Thanks tony

[LinuxBIOS] USB 2.0 booting
by Jun OKAJIMA 31 Mar '05

31 Mar '05

Hello Linux BIOS developers. As far as I understand, current Linux BIOS does not boot from USB memory stick if it is USB 2.0, Right?. But, I also understand that EHCI (= USB 2.0) can also work as UHCI/OHCI( = USB1.1). Then, if I use a M/B which has EHCI and put USB 2.0 stick to it, and put Linux kernel supports EHCI driver there. And if I boot it with Etherboot/FILO with USB 1.1 support in this case, can it boot as USB 1.1? and can I switch USB mode to 2.0 after booting? What I want to do is like this. 1. Boot linux kernel by Etherboot/FILO/USB1.1 from USB stick. 2. Reading Linux kernel itself is slow. But after that, it works with 2.0 performance?. --- Okajima, Jun. Tokyo, Japan.
