To ALL: HELP!!! I left a message previously with no response… Can anyone help me boot my XT BB with an external 3.5" drive. I have it connected to an A3000 and I can't use the 5.25" drive. I have MS-DOS on the 3.5" so it will work if I can just get it to access the drive… -Tim Stonis

Tim: I believe that you will have to run 'set-up' and change the configuration to tell the BB that you have a 3.5" drive connected… but someone else who has first hand experience will really have to fill you in. – Whapp!ng from the North Coast Michael

I don't think that an MS-DOS machine can boot from drive b: It's either A: or the hard drive C:. When you connect a drive to the external port, it's drive B:. Probably the easiest thing to do would be to just hook up the 5.25" drive temporarily outside the 3000's case. Then use it to install the MS-DOS software on a Janus pseudo-drive.

Tim, Presuming your 3.5" drive is configured properly (drive 1, the A: drive) then you need a 720 or 360K disk to do the initial DOS install. Once you get DOS running, you can run setup to tell the system what the configuration of the drive really is. Don

Don, How do I configure and external drive to be the A: drive? -Tim

Tim: The internal drive will always be the A: drive (If I'm wrong… someome please jump in!). You can mount the 5.25" internal drive externally without further modification or, you can set it up temporarily, just so you can get your Jlink partition set up, and then run SETUP from msdos, and tell it that your A: drive is a 3.5" 1.44 HD drive, then save that config, shut it all down, and replace the 5.25" with the new 3.5". – Whapp!ng from the North Coast Michael

Michael… Tim is using an XT BB, so the setup doesn't apply, unfortunately. The XT BB has a connector for an external drive, and it can't be used as the "A" drive. Marion CROSSINGS Newsletter for the Bridgeboard, etc.

Tim, The only way to configure the external drive as the A: drive is to run the drive cable that normally goes to the internal drive …out the back and plug it into your external drive. The external drive needs to be set to drive 1 also (most usually are already set that way). Don

Tim, If by "external" you mean the Amiga external drive that connects to the external connector on the outside of the XT BB, it can't be done, unfortunately. The external connector is drive "B". I think you said you "couldn't use" the 5.25" drive. Why not? If you mean you don't have a drive bay for it, you can keep it outside in an external case, as long as you have the "internal" cables connected to it.

Marion, Actually…it can be done (using external drive as A:), but it does require a bit of work on the BB itself. You've got to cut and jumper 2 traces (I forget which traces exactly). That will swap the select lines from the internal connector to the external connector for A: (and make the internal connector for B:). Don

Don, Never say "never", right? If you ever see the details of how it's done, please drop me a note. I've been trying to find out, but nobody can ever tell me. Marion CROSSINGS

Marion, It's actually easy….if you've got a schematic. You look for the A and B select lines. Locate them on the board, cut them and jumper across them so that the A line goes to the B output and the B line goes to the A output. That'll make your external drive A: and your internal drive (if you have one) B:. Don
