You can't do it easily. ST412/506 MFM and IDE use the same port address and IRQ. You could try putting the ST412/506 MFM controller at the secondary port address and a different IRQ, but then your BIOS wouldn't be aware of it. Only OS'es that support a secondary ST412/506 controller to my knowledge are Unix based. Basically, it's more trouble that it's worth for DOS. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | What to buy? ** ARPANET : crash!pnet01!jca@nosc.mil | EISA or MCA? ** INTERNET: jca@pnet01.cts.com | When will the bus wars end? ** UUCP : {nosc ucsd hplabs!hp-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */
