    Default Bondwell B200 Laptop - Disk Issues

    Hi Folks!

    I've got a problem with a Bondwell B200 laptop that has me a little puzzled. It's an 80c88 system, 640k RAM and dual 720k floppy drives. The machine seems to work fine in that it boots DOS from floppy and can run programs. However, when I try to format a floppy disk, it only formats them as 40 track (360k)

    As the machine is an XT, there is no BIOS to change the drive type and there are no jumpers / dip switches to change. If I add the following into config.sys, it lets me format drives C/D as 720k without issue so I'm guessing it's some sort of software / configuration issue but not sure what to change. Any suggestions?

    device=driver.sys /d:0 /f:2 /c
    device=driver.sys /d:1 /f:2 /c

    Cheers,
    Dave

    Which DOS are you using? Is the boot disk being used 720k?

    Yep, 720k boot disk. Tried DOS 3.3 and 5.0

    It was the same with the early bios of the IBM XT, The floppy drive's were seen as 360k, If you can boot DOS 6.22, Run MSD and see what that says, You could use something like " Setdrive " or just stick with the driver.sys, I prefer Setdrive though, Actually i find it quite handy formatting 720k or 1.44M floppy disk's to 360k on occasions.

    I've just downloaded a copy of setdrive as that looks like the better option. I can keep using A/B instead of C/D for the drive letters. I remember the issue with early XT's (had to do the same on an Amstrad PC1512) but I would have thought this Bondwell would have just worked at 720k. Seems strange for a machine from 1989 to suffer from this issue.

    Cheers,

    Hmm, maybe it missed out on a bios upgrade ?, dunno
