WD1007A-WA2
DESCRIPTION
The WD1007A-WA2 controller interfaces up to two ESDI Winchester disk
drives with IBM PC/AT and compatibles and up to two 5-1/4 inch or 3-
1/2 inch floppy disk drives. Look-ahead caching and 1:1 interleave
significantly improve data through-put and reduce disk access time.
The feature 1 (F001) version includes the optional BIOS which
features shadow RAM. This shadow RAM feature allows the WFDC to
interface with all types of ESDI drives without modifying the system
BIOS. Option jumpers allow the BIOS to be mapped at one of four
address ranges.
The following is a list of common ESDI drives and their manufacturers
which have been reported to be compatible with the WD1007A-WA2
controller:
