" Take a look at the boot messages -- I suspect Xen hasn't got a
" proper driver for your IDE chipset and is falling back to PIO.

Yep, you are right.  Xenolinux says PIO.  I'll add this chipset to my todo list.

    ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
    ServerWorks CSB5: IDE controller on PCI bus 00 dev 79
    ServerWorks CSB5: detected chipset, but driver not compiled in!
    ServerWorks CSB5: chipset revision 147
    ServerWorks CSB5: not 100% native mode: will probe irqs later
        ide0: BM-DMA at 0x0700-0x0707, BIOS settings: hda:DMA, hdb:DMA
        ide1: BM-DMA at 0x0708-0x070f, BIOS settings: hdc:DMA, hdd:DMA
    hda: ST340016A, ATA DISK drive

" Are you sure you're using the same part of the disk?

most likely not.  I ran the scsi writes on two different hosts just as a
sanity check, and not as a rigorous check.  Both were the same hardware
and may even have had other users on them.  It was close enough to be labeled
'the same' for my purposes.
