It should, but you can't mount it in the U5 case. The box is too low.

I don't know and I don't care. The IDE chip in the U5 / U10 is the CMD
646. The Linux Kernel has a special option only to work around bugs in
that chip. I read on NetBSD/port-alpha that this chip has a somewhat
broken DMA, thus giving abyssal performance. => Don't use it.

I mounted a generic, cheap NCR / Symbios / LSI 53C875 PCI SCSI card and
it just worked.
