Step 12 Install the Operating System Driver
When booting the system from a drive connected to a MegaRAID controller
and using EMM386.EXE, MEGASPI.SYS must be loaded in CONFIG.SYS
before EMM386.EXE is loaded. If you do not do this, you cannot access the
DOS ASPI Driver The MegaRAID Express ASPI driver can be used under DOS, Windows 3.x, and
Windows 95. The DOS ASPI driver supports:
•
up to six non-disk SCSI devices (each SCSI device must use a unique SCSI ID regardless of
the SCSI channel it resides on. SCSI IDs 1 through 6 are valid
•
up to six MegaRAID Express adapters (you should configure only one MegaRAID adapter per
system if possible)
ASPI Driver
The ASPI driver is MEGASPI.SYS. It supports disk drives, tape drives, CD-ROM drives,
etc. You can use it to run CorelSCSI, Novaback, PC Tools, and other software that
requires an ASPI driver. CorelSCSI, Novaback, and PC Tools are not provided with
MegaRAID Express. Copy MEGASPI.SYS to your hard disk drive. Add the following
line to CONFIG.SYS. MEGASPI.SYS must be loaded in CONFIG.SYS before
EMM386.EXE is loaded.
