It uses an NCR53c400a - this appears to be supported by the ncr5380 driver.
I/O address of mine is at 0x290-0x29f, not sure about IRQ but may be 5 or
possibly 12 - if it uses one.
Look at the source of the ncr5380 driver for boot set up.
I have never tried using it in Linux so don't know if it will actually work.
