I am studying the LinuxBios project. I have a question about the RAM code: from Makefile, it seems that LinuxBios could load codes from FLASH to RAM twice, first for linuxbios_ram, second for so-called payload. My understanding is correct or not. However, also from Makefile, it seems that linuxbios is dependent on LINUXBIOS_RAM_ROM, but doesn't include it. The below is abstracted from a Makefile:
linuxbios: crt0.o $(INIT-OBJECTS) $(LINUXBIOS_APC) $(LINUXBIOS_RAM_ROM) ldscript.ld
$(CC) -nostdlib -nostartfiles -static -o $@ -T ldscript.ld crt0.o $(INIT-OBJECTS)
$(CROSS_COMPILE)nm -n linuxbios | sort > linuxbios.map.
So, there is no action on LINUXBIOS_RAM_ROM. Does it mean linuxbios_ram is not very important. Even without it, the system is also ok?
I try write my own code which changes Cas Latency on motherboard with AM2 socket (CPU AMD64 family 0fh, motherboard with original BIOS).
My program is on FLASH chip in network card, on address 0xFDEC0000. I put execution there and program works (I can see that FLASH is reading).
The program hangs when I set EnDramInit (reg. 0x7c, bit 31, function 2, device 24).
Address map configuration is set properly. Program is running from flash - why program hangs?

Can somebody please update the Filo README file to including the
following concerning CD-ROM device file syntax?
ie. CD-ROM device is to be specified as "hdc1" and not "hdc"!
Following are the relevant Filo documentation clippings:
According to: http://te.to/~ts1/filo/CHANGES
"* Support for mounting boot disk image of El Torito bootable CD-ROM.
("hdc1" means the boot disk image of the CD-ROM at hdc.)"
However, I only see a very vague reference for the syntax of specifying
CD-ROM drives within Filo's README:
"Notation of DEVICE for IDE disk and CD-ROM is same as in Linux (eg.
hda1 means the first partition of master device on primary IDE
With the above Filo README information, the user is going to think
"/dev/hdb" or "hdb" instead, FILO wants to see "hdb1"!

I'm new to the list and just wanted to find out about any socket F mainboard
bios' floating around.
I'm also working on a project to allow AMD Athlon FX-7x series processors to
be used on Opteron 2000 based boards. I've got the hardware, just need the
any insite would be GREATLY appreciated.

There are a lot of Cisco ce507 content engines going very cheap on the big
auction at the moment.
You can even pick one up on ebay for as low as ~$10AU if you are dillegent
enough watching the auctions.
Although they are obsolete for there intended purpose the hardware is very
The ce507 contain:
256 meg ram
symbios 83C895 with 18gig deathstar drive
asiliant 69000 video chip,
1 IDE port
i8042 kb/mous interface
2 standard comports.
2 intel e100 (82559) network interfaces.
The chipset is 443BX with a PIIX4E.
The bios is a general software job, possibly with video/mouse/keyboard
All video goes out the console port (com1) at 9600, as does the input from
The video and keyboard/mouse ports are availible via headers.
Although the kernel detects the i8042 and the asiliant video, I am unable to
get any video besides a cursor and no input from the kb/mouse happening.
The flash chips are 82F128J and a 82F400B and there is an altera EPM7032
sitting between them.
One of the flash chips is for the bios, the second is for the boot.
There is also a 93C46 1K microwire eeprom onboard.
If you access the bios at post and set the boot device to other than flash
you can boot floppy/ide/scsi.
In this way I have slack up and running on sda.
I also have zeroshell and ubuntu pyramid running off a cf card plugged into
I used a boot floppy and scsi cd to install slack.
After that long winded background my 2 questions are:
Has anyone managed to put openbios on one of these or similar boards?
Has anyone managed to access the boot flash on one of these or similar
If so, what is the proceedure?
