Memory clearing is only done for correctness. ECC memory does not work properly unless initialized. I think the Opteron setup now is down to the minimal needed for things to work. You only observe one reset correct? YHLU: One reset is right, but the output of the very beginning is not neat. > 1. AMD 8131: ioapic : PCI master mem/io enable.

As Ron mentioned later this needs a comment. In the general case we should not be enabling bus master DMA by default. I tend to remove bus master enables before remembering any special circumstances of the chip. YHLU: but the code in amd8131_bridge.c and not in general code. (devices dir) > 2.

Can we throw in a sanity check to ensure we don't run out of heap? I assume that is what was happening. Does the 4-way s4880 work? I'm not quite certain how my changes would affect it. YHLU: I will double check that, it not, need to increade the heap size again.

Eric, In the 1.1.6, you have move clearing memory from auto.c to k8/cpufixup.c. Is there any way to disable it for fast booting?

How does pre memory C code work on K8.
by maillists＠petrolhead.com 12 Mar '04

12 Mar '04

Something has been troubling me for some time which is how the code manages to run before the memory controllers are configured. The assembler I can see has no accesses to memory, but the C code does, is their some magic gcc switch that makes it be entirely register based? It's troubled me for a while one the memories up then I'm more than happy but before that I'm a little bemused. Many thanks Chris

Elitegroup ECS K7SOM+ supported?
by yfede 11 Mar '04

11 Mar '04

Hello, Is there any possibility to use linuxbios on a Elitegroup ECS K7SOM+ motherboard? Do I have to get it from the CVS repository directly? The link to the daily snapshot on www.linuxbios.org site doesn't seem to work: http://cvs.sourceforge.net/cvstarballs/freebios-cvsroot.tar.gz Thanks in advance, Fede.

Is there a list or site for ...
by Lancashire, Pete 11 Mar '04

11 Mar '04

sorry to bother every one with a non linux bios question I'm going to set up a small cluster at home for self education. cost as can be expected is a concern. For now i'm looking at a cluster of 4-8 boxes. I've looked at using used PC's but the best prices i've seen for anything with a >1 Ghz Processor is $200 or more. On the flip side Wal Mart of all places has a box for $200. No fancy or fast. but better then any used price ive come across. Anyway.. does someone know of a mailing list or site for those of us who have not won a lottery ? tia, -pete
