- I have two IDE harddisks (one Conner cp30104 116 MB and one Maxtor
- MXA-213 203 MB) that I'm trying to get to work at the same time,
- but my BIOS (AMI) refuses to find the second drive. My IDE controller
- claims to support two disks (there is even a jumper to remove to
- tell it there are two disks). I have specs on the Maxtor so I know
- how to jumper it to act as slave, but I don't have any info on the
- Conner disk. However, there are only three jumpers on it, with one
- jumper connector and I have tried all three positions, but in all
- positions but the factory installed one no HD is found, while in that
- position the second disk isn't found...
- Doesn't the Conner disk support a master-slave configuration?
- Do I have to do some magic with the cabling??
-
- If you don't know the answer to that one, try this:
- I actually have two IDE controllers and using the patches to wd by
- Tom Ivar Helbekkmo (tih@barsoom.nhh.no) I should be able to run
- one drive from each controller if I could only change the interrupt
- for one card (yes, and move the address space for the regs, but I can
- do that), but, you guessed it, neither card supports changing the interrupt.
- Now, if I only new the layout of the ISA bus (specifically, where is
- the IRQ 14 and say IRQ 15 line), I could hardwire the second card to
- use another interrupt.
- Could anyone please send me the layout?
- Which interrupt should I use (IRQ 15 as tih?)??
-
- As this question may not be of general interest, I guess e-mail answers
- would be best.
