AST RESEARCH TECHNICAL BULLETIN TB-0184 5-25-86
CC-432 AND ALLOY HARD DISKS
The purpose of this technical bulletin is to assist users
configuring systems that contain both the AST CC-432
communications card and an Alloy hard disk controller. Alloy
hard disks use interrupt 2 and I/O address 300. Since this is
the default interrupt and I/O address of the AST CC-432 card,
either the CC-432 card or the Alloy card must be reconfigured.
If you do change the interrupt and I/O address on the CC-432, AST
recommends using I/O address 340-34f or 360-36f. I/O address
320-32f conflicts with Alloy controller cards.
This information does apply to Alloy's Quicstor hard disk. If
you are using the Quicstor with a network or emulation product,
some Alloy dealers recommend using the PIO mode to format the
hard disk. Consult the Quicstor manual or call your Alloy
distributor for more information on the PIO mode.
