I have finally received my CD and have attemped to install 8+ times, with no luck. I keep getting problems with the disks

sd0(aha0:0:0); timed out aha0: MBO 02 and nor 00 (free) adapter not taking commands.. frozen?!

I have tried with 3 different disks 2 different 1542CF cards 2 seperate systems 3 different CD drives 2 different cables the newer boot.flp on freebsd.org

The systems were known working before I started, in fact the second system was running OS/2 happily before I started to canabilise it to try different hardware.

the origional system was running a 2.1.? release happily before I started this 'upgrade', and eventually stopped responding after it started to do the probe of the ISA bus.

My question:

Is there a known problem withthe 1542 drivers in 2.2.1 ? I know there were problems with the 2940 recently but have heard nothong about the 1542 being a problem.

I have never had these sorts of problems before with installs - just pilot error problems :)

I'm beginning to think that I'm jinxed!

thanks
