OS2.SYS

This is a driver for the Iomega ZIP-100 drives.

DEVICE=\OAD\OS2.SYS

These drivers only work for Iomega SCSI adapters and the Parallel Port version of the Zip 100 drive.

Attention: Newer Parallel Port Versions of the Zip drive don't work.

See also BASEDEV PPAOS2.ADD which should work with all parallel port ZIP-drives (100, 100+ and 250)

It works only with the older models. According to the readme file this drivers should support:

Iomega PC1600*, PC800, PC2, PC4 and PPA-I adapters
Bernoulli 230MB, 150 Multidisk, 90MB, 44MB, 20MB and 10MB drives.
Iomega LaserSafe, LaserSage Pro and LaserSage Plus drives.
Iomega Floptical drives.

Advantages

Fast without requiring the disk to be locked into the drive as a fixed disk.
Compatible with the format that the disks come with from the factory.
Only option for PP drive users with older OS/2 versions.

Disadvantages

Doesn't work with non-Iomega SCSI adapters.
Only allows one device to be attached to your SCSI adapter.
There have been reports of problems copying files that have large EAs and these drivers.
Drivers must be placed in a subdirectory named \OAD on the boot drive.

NOTE: Iomega SCSI versions of Jaz and Zip Drives can be used as backup devices with Seagate Backup Exec for OS/2 Warp. Cartridges used for backup will be reserved solely for backup use. For these devices, you must format the cartridges with the OS/2 format command from a command prompt. This format may fail if the Iomega drivers are loaded in the config.sys. If so, try commenting out the drivers, reboot, and try the OS/2 format again. Once the OS/2 format is complete, the Iomega drivers can be uncommented and there should be no further problem.

TIP: Together with HPFSREM.ZIP and - if you want a GUI - HPFSPM12.ZIP the drives can also formatted using HPFS. Both packages are available for FREE at: http://rheooptik.fmf.uni-freiburg.de/pub/os2/drivers/removables/00-index.html
