External 5 1/4" Drive Updated Setup Disk (250-1087) Software written for the CD-ROM is coded to look for Drive D. The original driver for the external 5 1/4" drive (on Multi-media computers) designated this drive as Drive D. Consequently, a conflict arises. The EXTSETUP.COM allows the external 5 1/4" drive to be designated as Drive B, thus resolving the drive designation conflict between the external drive and the CD-ROM. To verify that the updated setup file is being used, check the file size and date to make sure is matches the line below: extsetup.com 53612 7/12/93 2:09:04pm This disk contains the following files-- EXTSETUP.COM README.TXT You can use the external drive as Drive B as long as you do not already have a second floppy drive. It is not necessary to change the CPU setup for the second floppy drive, since the external floppy drive is not controlled by the floppy drive controller.
