SiS630 Software Watchdog Timer
by Spirit 18 Mar '03

18 Mar '03

Hello! I've been reading the SIS630 datasheet and found out that the chipset has a watchdog timer (for some reason they call it 'software') similar to that of the i810. Does anybody here know if there is a ready driver for that thing? P.S. I'm inspecting the datasheet in search for ways of disabling AC97 Audio and Modem functions, as that would be a great addition to the linuxbios. -- Best regards, Spirit mailto:spirit@reactor.ru

RE: ADLO for EPIA

Thanks. It works and I can see something (just splash of colors) on my CRT. The screen, though it is not usable, is brought up by original VGABIOS using ADLO.

With current linuxbios for EPIA, I found that internel graphic device (bus 1, dev 0 ) is not visible in the pci configuration space. I have tried to enable this by setting PP_Rx3E and RxA9 registers, but with failed. Do you know how to make it visible? Heechul > In the current cvs tree, vga is not enabled.

serial console problems
by Alexander Amelkin 16 Mar '03

16 Mar '03

Hello! I already asked, but nobody answered my question. I'm having problems with the serial console when booting LinuxBIOS on a pcchips m787cl+ motherboard. The serial works for output (I can see what the box says) but doesn't for input (I can't login from the serial console). If I boot the same kernel with the same parameters (console=ttyS0,9600n8) using the original motherboard's BIOS (AMI), I don't have any problems at all. Any suggestions? With best regards, Alexander mailto:spirit@reactor.ru

Patch to flash_rom
by SONE Takeshi 16 Mar '03

16 Mar '03

Hi, I modified the flash_rom program a little and it might be useful for others. - Add "enable" for VIA VT8231 (southbridge of EPIA board) This does same thing as what is in src/mainboard/via/epia/README. (Btw, I downloaded the datasheet for VT8231 from here: http://www.google.com/search?q=vt8231+application%2Fpdf It's publically online ;-) - Fixed segfault when no "enable" is defined for a board. - Fixed delay calibration so it really finishes in a second (original code takes up to … [View More]100 seconds theoretically, >10 seconds on my box) - Support for -r (read), -w (write), and -v (verify). Writing is not really tested since I don't have my BIOS Savior yet. Looking forward to trying out LinuxBIOS on my box.

problem with udelay solved - romimage too big
by Alessio Sangalli 14 Mar '03

14 Mar '03

Hi, mucking with the source cde and with configuration samples I've solved the compile problem I wrote about yesterday night (udelay) Now I can get a romimage file. I plan to burn this file inside the normal flash of my pcchips 810 board to boot from IDE (hard disk). However, the file romimage is too big! I would have expected a 256KB file, but I obtain a 1.4MB one: $ ll -h payload.block linuxbios.rom romimage -rw-rw-r-- 1 alesan alesan 64k Mar 14 13:31 linuxbios.rom -rw-rw-r--… [View More]

Newbie question
by Yann POUPET 14 Mar '03

14 Mar '03

Hi, I've read a lot of posts, but haven't found what I'm looking for. I think I've understood that linuxBios is only there to be able to boot another Linux. Is it possible to boot the kernel directly in (from?) the bios then launching init, mouting HDs... I mean, is there a way to do as if there where no bios on a pc, decompressing the kernel just after power-on, and going on? I'd like to do this, and 8MBytes millenium doc could maybe help me. Actually I just need a fast booting system. Hope … [View More]
