I had a dickens of a time myself and finally ended up removing *all* the 5.0.2 stuff and starting over from scratch. Most of my problems stemmed from an old Rev A Applied Engineering GSRam that according to AE is *not* DMA compatible and cannot be made DMA compatible unless you'd like to mail them your fully populated card and $99.00 for a DMA capable version. I also found that some of the older Transwarp GS cards are not DMA compatible and the new chip to fix that problem can be had from AE at no charge. You can tell the difference by looking at the top right corner of the TWGS and examining the chip marked TWGS2. That chip should have a B rather than an A on it for DMA compatibility. The high speed SCSI card is also not going to like some of the older eight foot long CMS SCSI cables either. I had to dig up a shorter one and move "Howler," my old 20 meg harder closer to the machine. I like the card though but cannot tell the difference between DMA on and DMA off right now. At this time I've got an old Apple ramcard in the machine with DMA on but am going to have to plug back in my GSRam sooner or later since I have grown used to the program space. Has anyone used a GS Juice 4 meg card with any luck? Their $299 for four meg and my recent conversations with AE concerning their memory cards have made me think of making a change. -- Paul Hutmacher | paul@nuchat.UUCP |Sometimes the only thing a P.O.

I have the new SCSI card and would like to know what program anyone is using to Low Level the drive. I have a 84 meg drive on a IIGS and a TWGS. Before I got the new SCSI card I used SCSI Hacker to format with but now I can't get it to run with the new card even with DMA turned off. (The program crashes.) Any help is greatly appreciated. Don't blame me... I only work in the Oil Patch. Rockey Stanaland ProLine: Pro-Abilink

Plug the old rev c SCSI card and low-level format to what-ever interleave you want, the high-level (ProDOS format/initalize), partition, than plug the DMA SCSI card and you're ready to go.

The only flaw with this is most of us do not have an "old" card laying around to plug in. I upgraded my system from a CMS SCSI card to the DMA SCSI card. Perhaps someone can tell us what interleave the partitioning software that came with the controller leaves us with. -- Paul Hutmacher | paul@nuchat.UUCP |Sometimes the only thing a P.O.
