I recently purchased a Zenith Z-181, which I'm attempting to equip with an EXTERNAL 5 1/4" drive. I've set the dip switch to indicate 2 internal and 1 external drive and loaded driver.sys with the following parameters: device=driver.sys /d:02 /c /f:0 The problem is that the system installs this drive as BOTH drives C: and D: This screws up my batch and autoexec files, which exect D: to be a ramdisk. If I leave out the device= line in config.sys, the system recognizes the external drive as c: and allows me to read from it. However, it is imossible to write to it! Any help in straightening this whole affair out would be greatly apreciated. Max S. Robin AT&T Bell Laboratories Whiany Road Rm 7C-004 Whippany, NJ 07981 email:whuts!2212msr voice:201-386-6865

I've had problems adding extra drives with DOS 3.2 (havne't had to do it with 3.3 yet). There are complications too with whether or not the system BIOS already knows about 3-1/2 inch drives. I stalled a 3-1/2 inch 1.44 meg drive on an AST 286. I had to set the CMOS using SETUP first to indicate that a 1.44 meg drive was there. I was surprised that 1.44 meg was one of the options in SETUP-- guess AST is on the ball. Getting the drive to function required two entris in CONFIG.SYS. First, DRIVPARM = blah, blah, blah (don't have the dox handy, so I don't remember exactly what blah... was). Anyway, those were the parms for a 720K drive. The system belived it was drive B. If I used parms for a 1.44 meg drive, the system wouldn't recognize any drive B. Second, DEVICE = DRIVER.SYS /blah /blah /blah In this case, blah was the parms for the 1.44 meg drive. This drive was recognized as D: since a fixed drive was present. Putting in two DRIVPARM lines in CONFIG.SYS yielded an error message, so this was the only way this drive could be made to work in both modalities. Grrrr. Typical DOS braindamage I suppose. If anybody figures out a way to make the drive have the same letter for both densities, I'd be interested in hearing too! Season's greetings, Bill
