- I have not problems using OS/2 with Adaptec SCSI controllers. I'm using OS/2 on
- 2 machines with SCSI controllers. One is a PS/2 with the Adaptec 1640 and the
- other is a Dell with a 1542. The Dell is a 486/50 and it screams! The PS/2 has
- an internal 60 meg hard drive and an external 213MB scsi hard drive. The
- external drive is about 2-3 times faster than the internal.
