Thanks, It works.

Just mark the asm as volatile and the code will work fine. Eric

Eric, the current romcc seems have problem to process "asm". Or bist cause the problem?

Where can one access the LinuxBIOS source code for the Tyan S2895 mainboard (dual CK8-04 chips)? ------ I asked about CK8-04 chip support a rather short time ago in this thread: http://www.clustermatic.org/pipermail/linuxbios/2004-June/008326.html Thanks again Ron and David for your responses and especially YhLu for this very encouraging response: http://www.clustermatic.org/pipermail/linuxbios/2004-June/008328.html Again, I must say that was very quick work for such a new chip!

Errors on download page?
by Liu Tao 31 Aug '04

Hello, I think on the download page http://www.linuxbios.org/developer/download/index.html the cvs host name should be cvs.sourceforge.net but not cvs.freebios.sourceforge.net? -- Regards, Liu Tao

USB Enable = PCI State Loss
by Jay Miller 30 Aug '04

30 Aug '04

Trying to resolve some issues on FILO w/USB support on a new board with Athlon64, 8151, 8131, 8111. It appears that when I turn on ohci, the USB controller probes for devices but the CPU loses all PCI state after it's enabled. As seen through HDT debugger. This is a new board, so I'm not ruling out HW as the issue, but I'm just curious if anyone has seen this on their boards?

EPIA flash questions
by Joshua Wise 29 Aug '04

29 Aug '04

Hi folks, Well, I finally got myself a Linuxbios supported board (an EPIA ME-6000). Later tonight I'm going to order a flash from Mouser to swap out, but before I do, I have a few questions: On board is a PLCC form factor 39SF020A. Mouser also carries the 39SF040A, which is a 512k ROM. The pinouts seem to be the same, but I'm not sure whether the extra address lines are carried out anywhere. Does anyone know whether the EPIA will be able to use the extra 256k? Also, I was not planning on getting a BIOS savior. Does anyone have experience with hotswapping flashes on the EPIA? Will bad things happen if I do? Do I need to make myself an external board with chip select lines, or can I just hotswap? Thanks, joshua
