haiupdate.gz is an update to the Mark Williams hai driver for people with adaptec aha-154xA or C cards and the cards compatible with the adaptec aha-154x series of SCSI host adapters. It is for use with Coherent 4.2.05 or later and is included in Coherent 4.2.08. To install this fix you must have Coherent running on your hard drive. To do this you may install the aha driver (The alternate driver without tape support) from the installation disks and apply this fix to generate a new kernel. Notes: If you are using a 1.0 GB disk on an aha-154xC and have the extended BIOS turned on you cannot install this patch. For details write to support@mwc.com. There is a problem in the instructions included with this fix. To install it you must disable the aha and enable the hai driver after installation by typing: /etc/conf/bin/idenable -d aha /etc/conf/bin/idenable -e hai from the shell prompt as root. -Chris Hilton .
