I wanted to transfer a bunch of files to my 486 using my zip drive. Copied all the desired stuff to a disk using a Win98 PC, so the zip drive is working.
The 486 however doesn’t seem to like that drive. It’s an 5x86 133 with Soyo PCI board (and even 1 VLB slot 🙂). Its has an onboard controller, 32MB RAM and DOS6.22
I checked the config.sys and Lastdrive=G should be good for the 3 drives, including a CD-ROM drive, I am using in that machine.
The iomega did work well the last time I used it with a Pentium 233MMX that only has DOS6.22 on it - no Windows.
It’s a parallel port zip drive, that port is also active in the 486 BIOS and shows up while booting. Since it uses IRQ7, just like the installed GUS Classic, I booted the PC bypassing autoexec and config but that didn’t change anything, I still get: No drive letter assigned.
Any ideas?

Have you installed the drivers?

Vogons drivers should have the archive as well.

IIRC you have to use the combo DOS tools and DOS drivers.

PC#2 PIII-1Ghz - 98SE/W2K

I got the DOS drivers but I didn’t know which one to use so I tried the included GUEST.EXE first and yeah, that worked.
Probably another version than I used before…weird but hey, it works now so all good.
