Recommended Motherboards to use w/ Linuxbios List
by Roger 14 Nov '03

14 Nov '03

One piece of data missing from the linuxbios status page (listing of compatible motherboards), is a "recommended motherboards" section to use with linuxbios. It seems that some features of motherboards do not work fully currently (ie vga, etc), and this data does not look to be fully documented on the status page. Basically, I'm planning on building a box for my parents to use explicitly for email/web (rather then relying windowsxp virus prone o/s). I want to stick with the Intel cpu, however, per your recommendation, I will sway to amd (although i currently have all intel cpu's with source already complied for intel x86). To make it simple, should i just buy a (intel) mobo from cwlinux? -- Roger http://www.speakeasy.net/~rogerxx/index.html

sis645dx

Hi, I want to run linuxbios on a sis645dx board. I think there is no support for this chipset. Can someone give me some advice about: - compatibility with sis630 or other supported chipsets - Is it a good option to copy necessary parts from original bios and past into linuxbios?

LinuxBIOS and ISA slot on PCChips M787CL M/B
by riskin＠esinosoft.com 13 Nov '03

13 Nov '03

Hello ron, I am migrating LinuxBIOS from vt5426 to PCChips M787CL( NB: VT8601 ,SB: VT82C686B),and I want to use ISA slot.I think that LinuxBIOS doesn't need to initialize ISA slot, the devices on ISA bus should work,but I am wrong.So does LinuxBIOS need to initialize the ISA slot? Any advice is appreciated! riskin

Re: LinuxBios + etherboot 5.0.11
by Dave Ashley 13 Nov '03

>Boot from (N)etwork or from (L)ocal? 0 This is a bug in etherboot, it is getting a divide by zero error. As I recall it was related to etherboot trying to use the normal pc bios to get the current time, and the time isn't changing, so you get a divide by zero or some such. Don't know if it is a bug or a configuration setting. Actually I dug deeper and found a patch to etherboot 5.0.10 that we're using. In src/timer.c in the function currticks that doesn't just have a single return, add this line: { unsigned long clocks_high, clocks_low; unsigned long currticks; +setup_timers(); /* Read the Time Stamp Counter */ rdtsc(clocks_low, clocks_high); The CONFIG_TSC_CURRTICKS seems to be related in some way. -Dave

LinuxBios + etherboot 5.0.11
by Xavier Pegenaute 13 Nov '03

13 Nov '03

Hi, now i'd like to try with etherboot, i just compiled bin32/via-rhine.elf modifying the Config file like the FAQ of LinuxBios. I put it like a payload but id does'nt work, just reboot. The config file of linuxbios is the example. And the output is this: ---------------------------------------------------------- Welcome to elfboot, the open sourced starter. January 2002, Eric Biederman. Version 1.2 37:init_bytes() - zkernel_start:0xfff00000 zkernel_mask:0x0000ffff Found ELF candiate at offset 0 New segment addr 0x94000 size 0x7188 offset 0x80 filesize 0x3680 (cleaned up) New segment addr 0x94000 size 0x7188 offset 0x80 filesize 0x3680 Loading Segment: addr: 0x0000000000094000 memsz: 0x0000000000007188 filesz: 0x0000000000003680 Clearing Segment: addr: 0x0000000000097680 memsz: 0x0000000000003b08 Jumping to boot code at 0x94000 ROM segment 0xfdc4 length 0xfffe reloc 0x9400 Etherboot 5.0.11 (GPL) ELF for [VIA 86C100] Boot from (N)etwork or from (L)ocal? 0 LinuxBIOS-1.0.0 Wed Nov 12 14:02:46 CET 2003 starting... ----------------------------------------------------------- The 0 after (L)ocal? is just the start of reboot, is there any way to debug in etherboot? I have'nt seen nothing about. Some hint? Thanks a lot. Xavi. PD: Changing etherboot by Filo works perfectly.

Re: Help on epia-m 10000 linuxbios VGA
by Dave Ashley 13 Nov '03

13 Nov '03

> Santi Mirenna >In attach you have the output log .... >Can someone tell me where i wrong? You haven't applied all the patch, specifically the handler for the unsupported bios interrupts. This is the bug where it just gets into an endless loop of bios interrupts, so the program needs to exit the bios somehow. -Dave
