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.
