My sb2500 boots from a CompactFlash card in an adaptor plugged into the
unused onboard ATA port ( the other one is hooked to the DVD drive ).
It's only UDMA33 but just for loading the kernel and a rescue system
that's more than enough. For everything else I have a 500GB SATA-II
disk on a Silicon Image PCI-X card, sitting in one of the 66MHz slots
so there's plenty of bandwidth to go.
The adaptor is ~$5 at monoprice, the SATA card was about $20 or so.
