(MCP51), latest BIOS (dated 11-2007) Ok, I finally got it working. The problem was 32/64 bits issue. I'm so used to 64bits kernel and 32bits userland - not a single thought occured to me that this might be problematic of some sort. I was always trying 32bits kvm usermode tools with 64bits kernels. Now I booted a 32bits kernel, and it finally worked. Oh well. /mjt ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
