I know I'm hijacking a thread here, but I have a box thats running my
milling machine that resembles this particular duck in that it will not
willingly tolerate a drive set as slave on the primary interface,
corrupting both drives at the drop of a very small hat. This board, a
mach-speed, has this ide controller on it:
0000:00:11.1 IDE interface: VIA Technologies, Inc.
VT82C586A/B/VT82C686/A/B/VT823x/A/C PIPC Bus Master IDE (rev 06) (prog-if
8a [Master SecP PriP])
Subsystem: VIA Technologies, Inc.
VT82C586/B/VT82C686/A/B/VT8233/A/C/VT8235 PIPC Bus Master IDE
Flags: bus master, medium devsel, latency 32
I/O ports at dc00 [size=16]
Capabilities: [c0] Power Management version 2
After removal of the slave drive I was trying to dual boot from, that box
is as solid as a rock. So take this for whatever its worth. I also
haven't tried it as hdd because the cables won't reach due to the drives
position in the case.
