Preconfiguration Information

Adaptec AHA-1542C and AHA-154CP only: If only one adapter is installed, use default configuration parameters in both basic and advanced modes.

Adaptec AHA-1540CF only: The DMA transfer rate should be left at the default unless your motherboard supports higher rates.
If installing more than one adapter, enable the BIOS on both. If Plug and Play is disabled on the host system and a mix of Plug and Play and non-Plug and Play adapters is installed, ensure that the non-Plug and Play adapters do not use default values for the I/O base address, DMA channel, and IRQ level.

AHA-1542C, AHA-1542CF, and AHA-1542CP only:

o Synchronous Negotiation:	Disabled for each CD-ROM drive target
o Support for More Than Two DOS Drives:	Disabled
o Dynamically Scan SCSI Bus for BIOS Devices:	Disabled

For two non-Plug and Play cards:

o I/O Base Address:

230 and 330 only

Because the Adaptec AHA-1542CP and the Solaris fdisk program may be incompatible, use the DOS version of FDISK (or equivalent utility) to create an entry in the FDISK partition table before installing the Solaris software. Create at least a 1-cylinder DOS partition starting at cylinder 0. If the DOS partition is not created, the system won't reboot after Solaris installation.
If more than one adapter is installed, the system can only be rebooted with the boot diskette.
Two Plug and Play cards are not supported in a non-Plug and Play host system.
