i have played with two version of install software, no luck with either: supraboot II v1.02 supraboot II v1.09f the problem is this: power up the drive. (wait for heads to settle) power up the a500 with the supraboot disk in drive 0. ^D so its doent hang on a supra mount, drive has never been amiga formated. supraformat after supraformat loads it immediately trys to talk to the drive and sets the drive and controller to "other" and sets the lowest cylinder to 0 and the high to 1. the drive light goes on and the format util seems to be locked up it wont let me exit or do anything but the mouse still works. ?????????????????????? The drive is a CDC 94161-86 i dont have the specs for it but was wanting to play with low numbers for formating specs. as it is, even if i had the real numbers it would do me no good since its hanging on the format pre-lims. i would also like any comprehensive lists people may have for harddrive specs, i heard someone posted such a list a year or so ago. anyhelp appreciated thnx

The jumpers on the drive are probably set wrong. I had similar problems until I changed the jumpers. Mine had originally been jumpered to not spin up the drive until told to, which is not what supra expects. It had also been jumpered to the wrong unit number. Lastly, you probably need to add termination resisters to the drive. Drives intended for e.g. Mac's are usually already terminated because generally people only use one. CDC drives are usually not terminated internally because they're often used in e.g. workstations with multiple drives, and a single terminator is added *externally*. The internal termination resister packs are dirt cheap and readily available. Doug -- Doug Merritt {pyramid,apple}!xdos!doug Member, Crusaders for a Better Tomorrow Professional Wildeyed Visionary
