Jennie,

This should be a super machine!

>They (Dell) will install (and support) Linux (RedHat 6.1)

One thing to ask Dell on this.  Since you can't shrink file systems in
Linux, you should make sure that the Dell installation doesn't use all
of the disk for Linux.  A good partitioning would be for 8 GB for Linux
and the rest for Windows.  50-50 would be good as well, but Linux has
had an 8 GB partition limit on IDE drives for some time (but check to
make sure that this is still true).

Lots of disk; lots of RAM; and a fast processor.  This should be a
super machine.

>Dell says that they
>have no problems with RedHat 6.1 and their video card and
>network card, but I was wondering if there is any performance

Not that I know of.

>Did you say you ran a system with the 15.4" Super XGA?

We have an Inspiron 7000 with a 15" XGA screen and McIDAS works nicely.

>Finally, the Unidata pages
>are a little out of date regarding what version of operating system
>is supported (just an observation, not a complaint),

Oops.  You are correct.  I should update the page to reflect the
successful use of 6.1 with all of our packages.

>but I read through
>the e-mail archives and see you mention RedHat Linux version 6.x,
>and you note having upgraded from some previous version to 6.1 without
>any problems.

Right, it all went pretty smoothly.

>So, I expect I am not the first person to try 
>running McIDAS under this version of of the OS?  

Right.  In fact, most Linux users are now at 6.1.  By the way, 6.2 is
now out, but I havn't had the chance to get and install it on my system
at home.  I don't anticipate any problems with 6.2.

>We are going to try to get this ordered tomorrow with the
>hope of getting McIDAS installed by the first week of June.

OK, I hope that the above comments are enough.

>I appreciate your input.  Hope the Madison meeting went well.

The meeting was good, and the stay after the meeting was very
productive.  We now have CIMSS products flowing to Unidata in a test of
my PNG compressor/uncompressor routines.  I have to make a couple more
tweaks and then cut a new ldm-mcidas distribution before I can switch
the products from the EXP feed over to MCIDAS.

On another note, I just got McIDAS-X 7.7 today.  Now, the fun begins!
