That's cool man. I think I was one of the last people to get a 2090A
and not be eligible for the upgrade deal for a 2091. The entire time I
had this Amiga I wanted to upgrade to a 2091 but could never get the
money together to do it. I finally managed to get one dirt cheep just
as the whole Amiga thing collapsed. I installed it, but never tried it
until now.
Ideally I want to get everything from the 2090A's drive over to the new
drive and then take the 2090A out of the computer. If I just copy
everything directly will it be able to boot from the SCSI drive, or do I
have to do something to make it bootable. Arg, I've forgotten how to do
all this stuff.

The 2000HD is the only Amiga for me. Non of this "accelerated" crap.
Its funny I no longer have a monitor for it so I'm running it through
my genlock to my 27" Sony VEGA. I've never see such a big 640x200
screen. Must try 640x400. I wonder how the VEGA will handle the flicker.

Right its not booting from the internal hard drives. It will boot from
a Workbench boot floppy. Both hard drives are visible when I do this.

You know I had trouble filling the 40MB hard drive, I think this 100MB
drive will probably do me for a while. Then again I don't know how
stable any of the stuff I have is, so it might be a good idea to have
something in reserve. You know for when I turn this thing on again in
10 years. :-)

Agreed. Hey, I have a spare SCSI CD-ROM drive at the moment. Cool, I
can put that in too. Although I have nothing for the Amiga on a CD.

How do I check that? I believe I have a relatively new 2091.
