Hello Kim-Ee, You've been the only individual to respond
(that I know of) on this subject, Thank you. I'll try
the 'compact' option in lilo.conf and see how it goes .
I haven't enough disk space on my fastest drive to be
able to get a reasonable idea of the thru put on this
controller , well I guess I could try that ide type
tester instead of bonnie . Using 'hdparm -tT /dev/sda1'
the Wide drive gets 'buffered disk reads' from 6.71 to
6.75 MB/s, the narrow drive sdb1 gets 3.61 to 3.66 MB/s
The above isn't a real test such as bonnie . these still
seem a bit slow for a drive/controller comb. capable of
bursts to 20 MB/s .
