This happened to me, too, on an SX with a Promise adapter, again with a
53C875 chip. It works perfectly in i86 machines, but the Alphabios seems
unable to deal with it at all, and hangs when it tries to detect the
drives. Putting a small boot disk on a different controller, and the
other disks on the 875 doesn't work, since the Alphabios still tries to
initialize the 875 when it boots, and stops cold.
Could the Alphabios be tricked into not probing for the 875? And would
MILO be able to initialize the device instead, perhaps?
