Well we're still pulling bugs out as you see.!

I do it all the time, are they the newest set (about a week old now)?
do you have a 386bsd partition ready for them to use?
It sounds as if they are being installed at location 0 on the disk
when they should be at the front of the BSD part of the disk.

Yes, it appears there is a bug in the 1740 under 1542 mode.
never fear, I have started on the 1740 extended mode driver.
I hope to have a working one by next weekend.

As I say, you should be able to. It's being installed wrongly
some-how.

I am running EISA with a bustek 742a controller. (the driver was
posted yesterday (or was it Saturday?)

The drive reports back, #cylinders, total capacity and # heads.

sort of an "Average" value.
