A1: I don't know. Whatever's on the motherboard. No plugin cards.
A2: PIO only. I wish I could say whether it's using mode3 or mode4.

Here's what hdparm says:

/dev/hdc:
multcount = 16 (on)
I/O support = 0 (default 16-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 787/64/63, sectors = 3173184, start = 0

I've tried different multcount and readahead settings and it makes
little difference.
