- 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.
