Via MVP4
by Jonas Meyer 23 May '03

23 May '03

Hi I've got this K6-2 that i haven'T used in months and would like to put linuxbios on. Chipset seems to be a MVP4 (vt8501) which i found some files for in the linuxbios source directory. But i'm still not sure if it is worth trying to replace the BIOS. I'd rather want to change the BIOS of my dual-P3 on a 440BX board, but as this is my primary machine i want to first do it on another. all the other Boards i have are intel FX Boards, which seem absolutely unsupported. I'd appreciate any help you can give. Thanks in advance Jonas Meyer

K7S5A (SiS735)
by Peter Kling 23 May '03

23 May '03

Hi, I would like to use linuxbios with my PC, but I'm not sure if my mainboard is supported or not. I've already read some articles about this mainboard and the chipset. Something about problems with using DoC. And SiS735 is "unstable" as I've seen on the status page. So, can somebody tell me which features exactly are suported with this mainboard? Perhaps somebody who has already tried to ise linuxbios with this mainboard. Or is there realy no support at all for my mainboard? Thx for any information, ciao, Peter

To add to Ron's message. It varies a lot with your experience and how dirty you want to get. A simple POST card and a lot of creative POST code bread crumbs is the cheap and dirty way to go, until you get the serial port debugger up and running. But it requires you to be really creative in crawling through the code. And takes a lot of time. But you can move up the a logic analyzer looking at bus cycles or an ICE (in circuit emulator) looking at CPU activity These two are expensive (lots of $10K), but you can often rent them. Setup is usually the time burner here. But with a LA you can take selective pictures of events chained together in time. I don't know if SIS has an ICE for their SOC products. Jordan PS: Has anyone done a USB interface low level debugger? Early BIOS or at least just prior to payload decompress.

Hello! My name is Vova! I from Russia! I want to put on the computer (with chipset SiS630, motherbord iei NOVA-7896) so-called fast loading Linux Slackware 9 using your LinuxBios program. I have downloaded (as is written in the instruction) freebios-20010708.tar.gz and mtd-20000704.tar.gz. For me a question on STEP 2: *************************************** ************************** - go to www.kernel.org and get linux-2.4.0-test12 o Once you have pulled this file down and untar'ed it, apply the proper patch from the freebios/src/kernel_patches directory. The patch is: *************************************** ********************************* For me Linux Slackware 9.0 with a nucleus 2.4.20. In the instruction ask to download a nucleus 2.4.0!!! What to me to do(make)? With what nucleus to work that ????? to place(install) LINUXBIOS!!! Help please! Yours faithfully Vova. __________________________________ Do you Yahoo!? The New Yahoo!

I cannot control my GPIO LEDS from the application
by Deepak Kotian 22 May '03

22 May '03

Hi, After booting from LinuxBIOS, I try to access the GPIOs connected to 7-Segmen LEDS, it does not do anything. Is there a way or something needs to be done in LinuxBIOS to enable it . If there are any experiences/suggestion, please let me know. Regards Deepak

EPIA + CONFIG_VGABIOS works
by SONE Takeshi 22 May '03

22 May '03

Today I tried CONFIG_VGABIOS. After a little bit of config hassle and fix to compile error, it just worked. Now I don't have to use ADLO. I put VGA BIOS in flash rather than enablnig PCI option ROM (it was just 0xFF 0xFF..). I like this code, it is great development. I should have tried this one first. -- Takeshi

Reverse engineering
by SONE Takeshi 22 May '03

Is it legal to disassemble the proprietary VGA BIOS to learn how to enable a particular VGA chip? Of course, he (who?) will not copy any bits from the copyrighted code, he'll just pick up register addresses and values, and its order. If he would eventually write a code to enable VGA this way, can we share the resulting code? -- Takeshi
