Step 14 Install the Operating System Driver
Important
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
boot drive after EMM386 is loaded.
DOS ASPI Driver
The MegaRAID DOS 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 adapters (you should only configure 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. 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.
