Seagate ST11R ST412 controller + Mitsubishi MR535R

Hello! I have an elderly Mitsubishi MR535R (60Mb-ish RLL) connected to an ST11R controller. The control and data cables are homebrew although neatly and tidying put together. When I power up an old Pentium II - because it's the only box I have with ISA slots - the ST11R pops up a message on the screen, clunks the drive in an "I'm accessing you" kinda way, but then reports "No drives found" and continues merrily on its way. The cables are straight-through, and I have the drive set to DS1. If I set the drive to DS2, the BIOS sits there for several seconds but doesn't access the drive. As my knowledge is a tad rusty, can anyone help identify what the problem here is? BIOS shadowing is off for the memory locations that are, and could, be used by the card. The only thing I can think of is that the ST11R is in fact an ST11M, tries to read the drive, goes "Uh-oh, don't recognise you" and reports "No drive found". Unfortunately I lack an MFM hard drive to test this out with :( Peter -- Peter Hicks | e: my.name at poggs.co.uk | g: 0xE7C839F4 | w: www.poggs.com A: Because it destroys the flow of the conversation Q: Why is top-posting bad?
