A bug was found in freebios2/src/northbridge/via/vt8601/raminit.c

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 06 Jul '04

06 Jul '04

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.

qemu target
by Stefan Reinauer 01 Jul '04

01 Jul '04

Hi LinuxBIOS hackers, I checked in a new target: emulation/qemu-i386 It allows to exchange the BIOS image of the multi target CPU emulator QEMU (http://fabrice.bellard.free.fr/qemu/) with a LinuxBIOS image. Since failsafe handling does not make much sense in an emulator, I only have one image built, with more space being available for the payload. The payload is about 155k, the image is 256k and LinuxBIOS occupies 64k, so there's quite some room left. Now, LinuxBIOS starts and executes all the romcc generated code in auto.c. But after that output suddenly stops. All of the resource allocation seems completely skipped. The first thing I get after this is when the payload has taken over. What can I do to get the output of the gcc compiled code again? In the beginning it did show these messages, but I was unable to reproduce this behaviour, unfortunately. I would guess it is not really skipped, since otherwise the payload is not executed. Attached see a log of the serial console and a log of port 80 activity. Can anyone point me into how to debug this? I am a bit confused. Am I using crappy compilers again? LinuxBIOS-1.1.6-OpenBIOS Mon Jun 28 16:54:53 CEST 2004 starting... Copying LinuxBIOS to ram.

The CPU is AMD Duron 600 MHz. Of course I use the fbdev X driver. The problem I have it takes 6.7 seconds to switch from console to X with <Alt><F7>. The 6.7 s time is very consistent, every time I measure it. It"s very long and annoying. The other direction (X->console with <Alt><F1>) its about immediate. During that 6.7 seconds the a rough outline of what is supposed to be on the screen is displayed. For example if the Galeon web browser is on the screen, then it displays the area where Galeon menus and other controls are in a block of grey, the area of the webpage in a block of black, and the URL box as a block of white.

LinuxBIOS and Win2K
by Mike Shields 29 Jun '04

29 Jun '04

Greetings, Mike Shields here. I am new to the list and to LinuxBIOS in general. I have searched the list archives and have read Adam Agnew's (et al) paper on booting Win2K on top of the stackable Open Source BIOS, as well as several other papers by William Arbaugh and coauthors on secure booting and secure BIOS. I am a consultant for SPAWAR (part of the US Navy) working on a project to make USN computers running windows more secure. I have been asked to give a short presentation to some SPAWAR and FNMOC people on June 29th as part of a project conference. The points I need to cover are the differences between current BIOS and LinuxBIOS and the advantages of the latter. We are trying to convince Dell (SPAWAR has a huge contract with Dell to supply computers to the navy) to give us the information to port LinuxBIOS to their systems. One misconception I must deal with is that many people think Windows won't load over LinuxBIOS (I have Adam's paper showing otherwise). I know very little about LinuxBIOS other than what I have read on www.linuxbios.org, my scans of the archive, and a short paper form Nicholus Andrews at Linux Labs. I was hoping to get some success stories on booting windows on top of LinuxBIOS, or other information I could use in my short presentation. Thanks, Mike Michael K. Shields, Ph.D. YarCom Inc. 350 S.

s: binary-file for Geode GX1 + Cx5530 & TFT
by Thomas Leidenfrost 29 Jun '04

Hi there, I'm using the AW-B651-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 I can simply flash? (the original Bios is backupped in a seperate ROM). Next thing is, that my board has two monitor-outputs, the ordinary 15-pole-DIN and a flatpanel-connector on the board? Is there support for the flatpanel-connector? Thanks in advance, Tom.

Using Cache As Ram for K8
by Li-Ta Lo 28 Jun '04

28 Jun '04

Hello, I have successfully used the cache in the K8 processor as RAM on the AMD Serenade mainboard. The cache as ram is used as a tiny stack space for the code generated by GCC which replace the need for a register only C complier like ROMCC. Now the whole LinuxBIOS C code can be compiled by GCC. There are few problems remaining. The first thing is I can only use 7 cache lines of cache (448 bytes) reliably in the K8. The access to the 8th cache line is unstable and the access to the 9th cache line hangs the processor. The other problem is the optimize_connection() function for multi-processor configuration runs unstably under CAR. It does not overflow the stack, it's just plain unstable for some reason. So I can only configure the mainboard as Uniprocessor. Is there anyone has any idea about these problems ? If we can solve these two problems, Cache As Ram can be used routinly for K8 and probably we can try to extend it to some other processors. YHLu, Do you have any dual K8 EVB with HDT pin out and works "perfectly" under normal (ROMCC) LinuxBIOS ? The ROMCC LinuxBIOS deos not work for the AMD Serenade board 100% (I still have the phantom device s problem) and the s2885 board we have does not have the pin out. Eric, What is the "effective" or "equalvalent" stack size of ROMCC ? Is 448 bytes of stack adquant for ROMCC "linted" code in general ? Ollie
