work linuxbios with openbios
by zhu shi song 10 Jan '05

10 Jan '05

How to use linuxbios together with openbios? Is there any clear howto doc? What's the main purpose of openbios? What's the main difference between openbios and filo? Now I'm using filo to boot my linux kernel. tks zhu __________________________________ Do you Yahoo!? The all-new My Yahoo! - Get yours free! http://my.yahoo.com

LinuxBIOS on the Intel 9IGLM motherboard
by Csányi Pál 10 Jan '05

10 Jan '05

Hi! I have the motherboard 9IGLM with Intel 845GL chipset. I know that this motherboard is not supported by LinuxBIOS (am I right?) but I ask you: what would be happen, if I would update the flash EPROM with LinuxBIOS? I run on my PC the MS Win2000 and Debian GNU/Linux Woody. And I have one more question: memtest86 v3.1 says: Unexpected Interrupt - Halting Errors: 261 905 Type: Gen_Prot I configured the memtest: Cache Mode: Always On Test Selection: All Tests Address Range: Test All Memory Memory Sizing: BIOS - All If in the configuration the Memory Sizing: BIOS - is not All, then the memtest not reports errors. Is my BIOS then defective or not? -- Thanks, and sorry for my English Paul -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.298 / Virus Database: 265.6.9 - Release Date: 6.1.2005

flash rom utility

Is there a flash rom utility I can use to flash linuxbios to my EEPROM? Currently I am WICE to do it. But I can't depend on a hardware device to update bios. gin

Directory structure for x86emu
by Li-Ta Lo 07 Jan '05

07 Jan '05

Hello, It turns out that the VGABIOS support can be made pretty generic for all kinds of PCI expansion ROM. So I have the emulator the .init method of default_pci_ops_dev. I am going to add the following directories, if there is no objection, I will commit it next week. src/include/x86emu -- public header file of x86emu src/devices/pci_rom.c -- expansion ROM loading and execution src/devices/emulator -- the emulator and supporting functions src/devices/emulator/x86emu -- the emulator itself src/devices/emulator/pcbios -- legacy PC BIOS handler for the emulator src/devices/emulator/biosemu.c -- glue between pci_rom.c and the emulator Any comments ?

low level shell
by Bryan E. Chafy 07 Jan '05

07 Jan '05

Apologies if this is a redundant contribution. None of my pc motherboards have JTAG or HW debug capabilites. And constantly (hot)flashing, changing ram init code, then (hot)flashing again gets old really fast. Looking around, I couldnt find any debug tools that would operate at basically the reset vector level. I thought this was the goal of openbios, but I got lost in all the jibberish about 4th and firmware standards. So I set out to make a small interactive low level shell with the goal of providing at least some tools to aid in board/memory bringup and debugging. This was nontrivial given the system limitations, however I got a few things to work. Attached is llshell.inc (for linuxbios1, Ive not tried any of the new stuff yet) and llshell_linux (for running/testing inside of linux). It's written entirely in asm and can run in a memoryless early stage (say at the beginning of ram_set_registers or points afterword). List of commands: beep -- pc speaker beep rst (or RST) -- reset out(b,w,l) <val> <port> -- raw out val at port in(b,w,l) <port> -- show raw port value jmp <address> -- jmp to address (llshell addr is in eax) call <address> -- funcion call (assumes a working stack) cli -- clear interrupts sti -- enable interrupts push <value> -- push value onto stack pop -- pop from stack and display wm(b,w,l) <addr> <val> -- write mem dm <addr> <lines> -- dump mem mcp <src> <dst> <size> -- mem copy mpat <pat> <dst> <size> -- mem pattern memt <begin> <end> -- memory test pcir(b,w,l) <loc> -- pci read config pciw(b,w,l) <loc> <val> -- pci write config dl <addr> <size> -- memory download (display xor cheksum at completion) cram <addr> <size> -- enable cache to be ram (experimental) baud <val> -- change baudrate (not yet implemented) exit -- exit shell All values in hex (0x prefixing ok)

RE: Directory structure for x86emu

Also it should be controlled by some CONFIG_X86EMU....in case it is not needed by some configuration. And if CONFIG_CONSOLE_VGA is enabled, it should be automatically enabled YH -----Original Message----- From: ebiederman(a)lnxi.com [mailto:ebiederman@lnxi.com] Sent: Thursday, January 06, 2005 6:31 PM To: Li-Ta Lo Cc: LinuxBIOS Subject: Re: Directory structure for x86emu Li-Ta Lo <ollie(a)lanl.gov> writes: > Hello, > > It turns out that the VGABIOS support can be made pretty generic > for all kinds of PCI expansion ROM.

Except for plug in video cards I don't think this is a direction we want to go in. So at least for now pleas don't make the emulator the default .init method. > src/include/x86emu -- public header file of x86emu > src/devices/pci_rom.c -- expansion ROM loading and execution > src/devices/emulator -- the emulator and supporting functions > src/devices/emulator/x86emu -- the emulator itself > src/devices/emulator/pcbios -- legacy PC BIOS handler for the emulator > src/devices/emulator/biosemu.c -- glue between pci_rom.c and the > > emulator > > Any comments ?

Attic gone?
by Stefan Reinauer 06 Jan '05

Hi, I want to look at some old files I checked into LinuxBIOS CVS a looong time ago, implementing LDTSTOP_L. But SF's ViewCVS does not show the Attic anymore.. is there a trick to get them? Stefan

RE: VGABIOS is working under LinuxBIOS

After all devices initialized, call do_vgabios? YH -----Original Message----- From: Li-Ta Lo [mailto:ollie@lanl.gov] Sent: Wednesday, January 05, 2005 3:41 PM To: LinuxBIOS; ron minnich Cc: Greg Watson; Stefan Reinauer Subject: VGABIOS is working under LinuxBIOS Ron, I just got the vgabios emulation working in the LinuxBIOS. The VGA card is complete inited before the kernel is loaded. Now I have vga console just like normal bios system. I will try the reduced x86emu and see if it works too.
