Q: How do I get my ncr53c8xx scsi controller to transfer > 10MB/s for my disks?

A: If the driver is compiled into the kernel, then edit /etc/lilo.conf as
follows:

append="ncr53c8xx=tags:4,sync:10,ultra:y"

Note: Thanks to Don Holmgren for the answer.

If one is using modules, then add the following line to
/etc/conf.modules after the line "alias scsi_hostadapter :

options ncr53c8xx ncr53c8xx="tags:4 sync:10 ultra:y"

All the options available to the ncr53c8xx driver as well as their defaults
can be found in the /usr/src/linux/drivers/scsi/README.ncr53c8xx. Of course,
you will probably need to have the linux kernel source loaded to read this.
