freebios1 sis-kernel_patch for 2.6
by Thomas Wehrspann July 8, 2004

July 8, 2004

Hi, i'm still using the K7SEM Motherboard with DiskOnChip Milleniuim an LinuxBIOS. Linux 2.6 has some features i need and want, so i ported parts of the latest 2.4 sis-kernel_patch and the ide-spinup.patch to the 2.6 kernel some time ago. I combined both patches into one. I didn't port the SiSFB-Lite part of the SiS-Patch, because the SiS graphics driver in the kernel changed a lot. The SiS framebuffer seems to work better with kernel 2.6 and linuxbios than it was with kernel 2.4 and linuxbios. But i have to call the fbset utility first after booting with linuxbios. I do not have the knowledge to fix that. Greetings Thomas Wehrspann

Linux bios and IBM Netvista 8363-EXX

Hello I'm curious if a IBM thin client (8363-EXX or Netvista 2200) can use linuxbios? Thanks for any info

You may only disabe normal instead of fallback. LB will execute failover at first. -----邮件原件----- 发件人: Simon Xin Cheng [mailto:scheng@msica.com] 发送时间: 2004年7月7日 15:43 收件人: Takeshi Sone 抄送: Simon Xin Cheng; linuxbios(a)clustermatic.org 主题: Re: A bug was found in freebios2/src/northbridge/via/vt8601/raminit.c > Maybe the memory map information is wrong. > (FILO tries to relocate itself to non-existent RAM area and crashes?) > Are you sure you have 160MB RAM and none of it is allocated for > framebuffer? > You should run memtest86 as payload so you can see if memory > configuration is ok. > > -- > Takeshi > Takeshi, Thank you for your suggestion. I tried memtest86-3.1.a. This guy creates a 69356Byte elf file. It exceeds 64KB. So, I disabled fallback. However, I can not boot from the romimage I created (i.e. cann't get any information from serial console). Following is the configure file. If you have time, would you please check it.

A bug was found in freebios2/src/northbridge/via/vt8601/raminit.c
by scheng＠msica.com July 7, 2004

I am trying to use LinuxBIOS V2 + Filo to boot local Linux on hard disk (EPIA 800 board). I found that LinuxBIOS executes an infinite loop in dumpnorth() function of freebios2/src/northbridge/via/vt8601/raminit.c . The function is: void dumpnorth(device_t north) { uint8_t r, c; for(r = 0; r < 256; r += 16) { print_debug_hex8(r); print_debug(":"); for(c = 0; c < 16; c++) { print_debug_hex8(pci_read_config8(north, r+c)); print_debug(" "); } print_debug("\r\n"); } } Since r is an unsigned char, it will never reach 256. To fix the problem, I simply added a line at the end of the loop: if( r >= 240 ) break; ******************************************************************* By the way, I am still working on filo. In my machine, after elfboot passing control to filo, LinuxBIOS Fallback restarts again. Following is a piece of screenshot: ......

Wanted: Binary File for the Gene 4312 w/ NS Geode & Cx5530
by Thomas Leidenfrost July 6, 2004

July 6, 2004

Hello, at the moment I'm using the Gene-4312-Board with the NS Geode CPU and the Cx5530. Reading the archive I found out, that some people were using a similar combination. So I wanted to ask, if somebody can send me a binary file that I simply can try to flash? (If it won't work, the original Bios is backupped in a seperate ROM). And Is there any support for the onboard-flatpanel-connector? Thanks in advance, Tom. -- Thomas Leidenfrost Corscience GmbH & Co.
