If you go to Compaq's normal support site you can muddle around until you locate "out of production" where you should find the CMOS setup software. Gridcase setups (if applicable) are at Tandy's support site. -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of LFessen106(a)aol.com Sent: Tuesday, February 20, 2001 3:19 PM To: classiccmp(a)classiccmp.org Subject: Re: Boot disk In a message dated Tue, 20 Feb 2001 4:11:50 PM Eastern Standard Time, "wschoppe" &lt;wschoppe(a)suffolk.lib.ny.us&gt; writes: << Sirs: Adrian Graham at the Online Computer Museum recommended I contact your group to try to locate a disk for my Compaq Portable 3. I realize it falls into the dinosaur category but someone gave it to me and the challenge of getting it operational was too much to bear. When it finishes counting all 640K of memory, it reminds me to use a setup disk or hit "F1". When I do that, it mentions there is a non-system or bad disk. Then the message keeps repeating when trying various type of DOS disks I have. I have the feeling Compaq uses something like DOS but I have none of those OS disks. Any help would be appreciated. Thank you, Bob Schoppe Although I don't personally have one, I believe you should be able to use a dos disk. The only caveat being I am pretty sure only has a 720k drive. If you can find a 720k disk, format it and put your favorite dos's system files on it and then try it. It may sound funny, but I just recently ran into the exact same problem with a GRiDcase 3. Works like a charm now :-) -Linc Fessenden
