AHA154X.ADD

Driver for the Adaptec AHA-1540/1542 SCSI host adapters.

BASEDEV=AHA154X.ADD <parameter>

Parameters

/V
/DBUFF - Loose access to RAM above 16M.
/A:0
/BON
/BOFF:8

TIP: By Prof. C.W. Fischer (Physics Department Director, CPES Micro-Computer Lab). Users may be interested in a undocumented parameter on the Adaptec AHA154x.add file i.e /DBUFF. Anyone using this SCSI adapter without /DBUFF will loose access to RAM above 16M. It's a Bus mastering problem on ISA (thanks to Steven Levine).

NOTE: When you use Seagate Backup Exec for OS/2 Warp, Version 3.0 with both a hard drive and a SCSI or QIC backup device connected you have to add - to avoid DMA errors - the following to your driver line to prevent BUS errors: /V /A:0 /BON /A:0 /BOFF:8
