Step 12 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 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 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 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.
device= <path> \MEGASPI.SYS /v
Parameters The MEGASPI.SYS parameters are:
Parameter Description
