That chip was a Via VT82C686B, and it is UDMA100. pciide(4) doesn't
claim to support this chip, so either the documentation's out of
date or the chip was being recognized as a VT82C686A. (As it's no
longer possible for me to boot off that motherboard, I couldn't tell
you.)

With that chip, this drive ran at Ultra/100 with no problems.

With an Acer labs M5229 controller, it's impossible to use DMA or
Ultra-DMA of any sort with this Maxtor 4G160J8.
