VIA EPIA
by Sorin Suciu 01 Jan '03

01 Jan '03

Hi, Can anyone help me with the procedures needed to setup LinuxBios for a VIA EPIA? Got the rom image and the kernel. I need to flash it but I haven't got the software. Is this process documented somewhere (as www.linuxbios.org ) does not seem to work and www.cwlinux.com documentation is not very explicit in this direction. Any help, suggestion would be greatly appreciated.. Thanks SS

Regarding the register values for the SDRAM intialization.
by sivakumar 31 Dec '02

31 Dec '02

Hi, I am porting the northbridge 82845e for my motherboard. While coding raminit.inc file, I took the file from the 82830 chipset directory and modified as per the requirement of the 82845e chipset. Now I want to know, How to get the register value of the regsiters, like DRB DRAM ROW BOUNDARY REGISTER and etc. Do I need to read these regsiter value from the system using normal BIOS? I could not find much details about the values in the specification. Is my assumption is correct? Thanks, Siva

LinuxBIOS hangs while copying the image from ROM TO RAM.
by sivakumar 31 Dec '02

31 Dec '02

Hi, The following piece of code is from crt0.base file. In my case it is hanging while copying the Image from ROM to RAM. From the serial output, it is sure that SDRAM testing is passed. But it hangs while doing movsb and rep instruction. I feel that value in the ecx register is getting corrupted and the loop runs for ever. Do any one faced this problem. #include "crt0_includes.h" CONSOLE_DEBUG_TX_STRING($str_after_ram) /* clear boot_complete flag */ xorl %ebp, %ebp __main: /* * Copy data into RAM and clear the BSS.

[COMMIT] flash.h flash_rom.c for BIOS Savior RD1-1M
by Andrew Ip 30 Dec '02

30 Dec '02

Checkin util/flash_and_burn/flash.h util/flash_and_burn/flash_rom.c added support to w29c011 which is on BIOS Savior RD1-1M. Note that it has only 128KByte which is more than enough for LinuxBIOS+etherboot. -Andrew -- Andrew Ip Email: aip(a)cwlinux.com Tel: (852) 2542 2046 Fax: (852) 2542 2036 Mobile: (852) 9201 9866 Cwlinux Limited Unit 202B 2/F Lai Cheong Factory Building, 479-479A Castle Peak Road, Lai Chi Kok, Kowloon, Hong Kong.

first attempt... almost. :-)
by Andrew Kohlsmith 29 Dec '02

29 Dec '02

I cut the trace, enabled flash and flashed it. I'm now the proud owner of a doorstop. :-) At the end of this email is a paste from the serial log. It boots, says it jumps to RAM, my HDD light flickers (I'm using the BOOT_IDE flag) and then it starts over again. A couple of questions: Is it saying it's happy with the system RAM? I do not have a kernel image at the location I said it would be at in the config file, which is why I _think_ that it is rebooting, but I thought there'd be some kind of log message stating something to that effect. My other question is one I probably already know the answer to: is there a serial-port flash util in LinuxBIOS? It's not a big big deal, I knew the risks going in to this but I'd like to try and get around desoldering a TQFP part and buying the adaptor (and socket) if I can help it. These motherboards were only $10, it seems silly to spend hundreds to reflash it. :-) (and yeah, the date is right... it's been over a month since I've been really working on it. :-) Regards, Andrew LinuxBIOS-1.0.0 Mon Nov 25 21:39:06 EST 2002 starting...

More questions...
by Nathanael Noblet 19 Dec '02

19 Dec '02

Hello again, I've been playing some more with existing configurations to figure out how to fix the tiara code to work in the linuxbios code for my board. I've got all the config files in place and a mainboard config file setup based on the example of others. I have placed copies of the common files like mainboard.c from other projects, just for the time being, until I have more of an idea what to put in them. I have configured a few of the other example boards to see how it all fits together and have learned a bunch. What I am now wondering about is the functions that are placed in the mainboard.c file. Are those mainboard specific? Where are they coming from? Defined in other files? How do I know whether I need them? Can someone explain to me what the purpose of the functions in a mainboard.c file are for? I'll keep looking. I have a funny suspicion that they are to setup the io and chipset and ram or whatnot. I haven't figure it all out yet, I'll be looking at more of the assembly for the actual function and where it came from etc... Any pointers would be nice. I think when I am done with this I'll help out with some docs for newbies coming from my perspective. I assume I send them to Ron? -- Nathanael Noblet Gnat Solutions 4604 Monterey Ave NW Calgary, AB T3B 5K4 T/F 403.288.5360 C 403.809.5368 http://www.gnat.ca/

Minit-ITX boards
by John Hearns 18 Dec '02

18 Dec '02

I have a hankering after buying a few (maybe 2 or 4) EPIA motherboards for experimenting with clustering and maybe Linuxbios. For use at home, in a small apartment. Don't know if I will REALLY part with the cash, but can anyone who has either an EPIA5000 or an EPIA800 board plese comment? The EPIA5000 has the advantage of being passive cooled and using a low power processor, but the specs says the CPU doesn't have as much horsepower as the C3 in the EPIA800. Any experiences with their noise levels, CPU power, etc. etc. gratefully received. Decisions, decisions...
