- Summary: I know it's possible, how to do it?
-
- I have a machine (486/25, OPTI chipset, AMI BIOS, ISA bus) with an ESDI
- controller installed. I want to switch to SCSI, but I'd rather not lose
- my ESDI drive immediately. I know that installing a SCSI controller without
- twiddling with the cards will create a conflict between IRQ's and I/O
- addresses; however, I've heard of people who've installed both types of
- controller on the same bus by changing the IRQ and I/O assignments on one
- or both cards.
-
- Does anyone know a good IRQ and I/O address assignment (= lowest possibility
- for conflict with my other cards -- a ThunderBoard, VGA card, and standard
- multi-I/O card) for this? Also, does anyone know a good SCSI adaptor for
- this kind of thing (= has jumpers or DIP switches with a wide range of values)?
-
- Are there any other problems I might run into? Don't worry about any
- problems that DOS will have with this; I stopped using that travesty last
- year.
-
- Please email responses to sinster@scintilla.capitola.ca.us, since I don't
- read this newsgroup.
-
- Thanks in advance.
-
- P.S.: It's alright if I can't boot from the SCSI drive(s).
