[LinuxBIOS] get some output on serial console of commel lv671 board, but not readable one
by Dieter Bloms 16 Jun '07

16 Jun '07

Hi, I managed to get some stuff on my serial out, when I switch on my commell lv671 board with i82801 chip and w83627hf superio, but it is not readable. The most of it are ? inverse colour like : ��SSQ��|��Ӌ��E��L��E��i��iT��i��[10;1H��Ϝ��Ϭ��ϼԜ��Ϭ��c߈�w�H�� I use 115200,8N1, which works fine, if I boot into linux with original bios. Has anybody seen those output and know what may be wrong ? -- Gruß Dieter -- I do not get viruses because I do not use MS software. If you use Outlook then please do not put my email address in your address-book so that WHEN you get a virus it won't use my address in the From field.

[LinuxBIOS] Specifications?
by Brendan Trotter 15 Jun '07

15 Jun '07

Hi, I'm wondering if there's a specification describing the state of the computer at the hand-off between LinuxBIOS and a payload. So far I've got LinxBIOS booting a dummy "for(;;)" payload in Bochs, and I've found out there's a "LinuxBIOS Table" and that it can be found by searching for "LBIO" in the first 4 KB of RAM and in the area between 0xF000 and 0xFFFFF. I don't know if there's a checksum or any other validation, and have been unable to find anything describing what this table contains. I assume there may also be ACPI, MP specification, PIRQ routing and/or (possibly) SMI/DMI tables, and I'm guessing that (if present) these tables can be searched for using the same methods as described in their corresponding specifications. There's also other issues, for e.g: - will an 80x86 system always be in 32-bit protected mode for 32-bit ELF payloads, and is long mode possible for ELF64 payloads (and if so, how is paging setup)? - are any parameters passed on the stack to the payload's entry function? - are AP CPUs started (or waiting for a SIPI sequence)? - can the payload assume anything about the state of the PIC, I/O APIC/s and local APIC/s, PIT, RTC, ISA DMA controllers, serial ports, etc? - what state are PCI buses and devices left in (would a payload need to do full PCI bus enumeration, or..)? - is there anything in the LinuxBIOS table that could be used to determine if the computer is "headless" and which serial port or other device to use if it is? - can anything be assumed about AGP and the first video card (if the computer isn't headless)? - is there any form of "LinuxBIOS API" that can be used by the payload for generic low level disk access (floppy/ATA/ATAPI/SCSI)? Thanks, Brendan

[LinuxBIOS] bigger flash part for via/epia
by Thomas Ekstrand 15 Jun '07

15 Jun '07

Hi! I want a bigger bios flash so I'm wondering, what is the maximum size possible for a flash memory chip to a via epia board? The original is only 256KByte. Any recommended part numbers are welcome! Thanks in advance! /Thomas
