To use a CD-ROM drive with NetWare 4.11, follow these instructions: load [pathname]\aha2940.ham slot=x load [pathname]\aspicd.dsk NOTE: If aspicd.dsk does not work, unload it and load it again. The first load initializes the host adapter; unloading and reloading allows the initialization to complete. load [pathname]\cdrom.nlm cd device list cd mount [number] or cd mount [name] The CD-ROM is now ready to be accessed as a volume. The Adaptec 78xx SCSI bus master firmware increases the SCSI performance of the Adaptec 78xx series host adapters under multitasking environments. The firmware uses a paging mechanism to handle up to 255 simultaneous SCSI commands. 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: max_tags=n In general, a low number for the max_tags option gives better sequential performance. 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.
