8-bit WD IDE adapter + CF?

Doc Shipley wrote: It was me. I'm using a Silicon Valley Computer ADP50 with a Maxtor 340MB drive as master and a CF-IDE adapter with 340MB CF IBM microdrive as the slave. This is on an IBM PC/XT (5160). Both the Maxtor and the CF push the maximum PIO over the bus, about 300KB/sec streaming reads. Some notes: - If anyone can find sources for ADP50s, please share. I only have one and I most definitely want at least one more. I am willing to trade hardware or a modest amount of buckazoids. - I could not get it to recognize all the geometry on a 504MB drive, which was surprising because I could've sworn such drives are under the 1024c 16h 64spt limit. It's possible one of those soft-BIOS tools (Ontrack? EZDrive?) might work, but I couldn't find a version that didn't require a 386 to run so I just went with the 340MB drive I had lying around. (I'm sure the actual code in the boot sector doesn't need a 386, just the install program. Had I not been lazier, I probably could have prepped the drive in another PC.) - Speed freaks: If you have a SCSI controller, such as Future Domain, you can go faster because the controller is memory-mapped. I believe Michael Brutman has clocked speeds of 500KB/s with his setup (on a PCjr, no less!) - Even with recognizing the full geometry of the drive, partitioning was non-trivial. The working setup right now is PC DOS 2K (IBM PC DOS 7.0 with Y2K fixes) and I believe I partitioned it with Ranish Partition Manager v. 2.37.11 (last version to run on 808x). The second drive, not needing a bootable primary partition, was much easier; native PC DOS 2K FDISK set the entire thing up as an extended partition + logical drive that covered the entire thing. MSDOS 6.22 works too. -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/
