Hi all, I haven't been able to boot a kernel (neither IRIX nor Linux) directly from the volume header on the ip27 (Origin 200). I can only load it from XFS partitions. I've looked at the PROM source, and figured out that the XFS loader loads in 64k chunks, but the volume header's loader loads in one big read. So, it's either failing due to a low timeout (old crappy hard disks!), or the "large" buffer size isn't supported. Anyone else experiencing this? Anyway, the end result of this is it makes Flo's hack for embedding a volume header on an ISO more Interesting. I'll try making a partition inside the ISO file system (overlapping with a file) which contains an XFS file system containing kernels... Cheers, Andrew
