Boisy,

I built another boot floppy with old
CC3Disk and current clock_soft+clock2.
Formats double-datarate just fine.
I get 1.31mb from a 3.5" floppy.
sct=20, sid=2,cyl=50 (hex of course).

[I changed the '.' to '*' to make]
[sure that it's booting from the floppy.]
[Cute trick to ID the boot source.]

I tried my standard boot where rb1773
(ident=$95F249) and clock_soft+clock2
are standard. When trying to format
HD (ie double-datarate) it gives 
error #250, busy something.

I'm using format where ident=$AC701D.

Please holler back during hours here that
I can test more (if you want). When I
go home, I don't have this setup available
for testing.
Right now it's ~8:03 AM PDT.

Paul - idezilla
