To use a CD-ROM drive with IntranetWare, follow these steps:

1.Load aha2940.ham by entering the following command line: ORDG￿>pathname@?DKD￿￿￿￿￿KDP￿VORW [

2.Load aspicd.cdm by entering the following command line: ORDG￿>pathname@￿QZDVSL￿FGP

NOTE: If aspicd.cdm does not work, unload it and load it again. The first load ini- tializes the host adapter; unloading and reloading allows the initialization to be completed.

3.Load cdrom.nlm by entering the following command line: ORDG￿>pathname@￿FGURP￿QOP

4.Enter the following line at the prompt, and then note the number and name of the CD that appears:

FG￿GHYLFH￿OLVW

5.Enter the number and volume name of the CD at the command line: FG￿PRXQW￿>number@￿>name@

The CD-ROM drive is now ready to be accessed as a volume.

The Adaptec 78xx SCSI bus-mastering firmware increases the SCSI performance of the Adaptec 78xx series host adapters under multitasking environments. The firm- ware uses a paging mechanism to handle up to 255 SCSI commands simultaneously. The sequencer can simultaneously manage up to 32 tagged, or 2 nontagged, SCSI commands for each SCSI device, up to a limit of 255 SCSI commands. The firmware can queue as many commands as the operating system is able to send to the host adapter. To set this feature, enter the following command:

PD[BWDJV n

In general, a low number for the max_tags option gives better sequential perfor- mance. This value varies with the level of random disk accesses and drive characteristics.

NOTE: A large value for max_tags can cause starvation problems with some drives.

Any error that occurs while the driver is initializing prevents the driver from loading. If an error does occur, the driver causes the system to beep and display a numbered error message:
