Umax wasn't alone with the IDE controller one channel issue. The Apple machines with IDE of that era had the same issues. This included the 630 series 68K machines among others. It even includes the Beige G3 series version 1 and 2. The third and final version of the Beige G3 fixed this issue. Ready for a bit more trivia? It turns out it wasn't really the cheap IDE controllers used by Apple and Umax. It is Mac OS 8 and 9 that limits the IDE to one channel. Any of these machines when made to run OSX will work with 2 channel IDE! Boot into OS 9 and the second drive disappears. Granted I only know one person running OSX on a Umax c machine. However a number of Beige G3 series 1 and 2 owners take advantage of being able to add that second drive for OSX use without needing a PCI ATA/ide card. later Will SFrom: Pastor Mac <[EMAIL PROTECTED]> Date: Mon, 1 Nov 2004 03:51:49 -0500 On Sunday, October 31, 2004, at 09:50 PM, Sean Jewett wrote:

The c series had an IDE port for only one device. Umax chintzed out so much that the IDE controller (normally master/slave--2 devices on one channel) was one device on one channel. Thus, the SCSI wasn't just there for compatibility but that was for the expansion. The CD drive was SCSI and normally set to 3. My old C box had a 40 GB IDE drive and all I did was set the drive jumper to 'master' and plugged it in. Apple Drive Setup saw it immediately and I partitioned it and away we went.
