Since this is my first posting, please forgive any glitches. Could any of you SCO 2.2.? 286 Gurus please help ? I have been running SCO Xenix 2.2.1 for 2 years on a 10 mhz 1 wait state AT Clone with an Award Bios and 3 meg of memory, A Miniscribe 6085 71 mb 28 ms Drive with a WD1003 2:1 interleave controller. Sometime ago I changed the controller to a WD1006 1:1 interleave and as with the old controller, the drive was diagnosed & initialized with Speedstore, to override the CMOS table which has no entry for the 1024 Cyl 8 Head configuration. These as well as the precomp (512) Landing zone (1023) 17 sectors, were entered during the XENIX Installation and all was well. I moved on to 2.2.3, and had no problems either. A week ago the box was turned of by mistake, and upon reboot, while the usual "fsck" was taking place, it ended up hanging. I decided to "clean up" the drive, and reinstall both the DOS as well as the XENIX systems on their respective partitions, as I have done many times before. The SPEEDSTORE program scanned the drive and found the same one bad cylinder that was always there, so that ruled out any new damage tp the drive. DOS was given it's partition and installed with no problems. All the DOS software as well as diagnostics of the Drive/Controller etc performed well and as expected. Here is what happens when I now try to install XENIX... The parameters are entered, the partition is created and activated, I proceed to do a quick scan, it scans about 3%, the drive led stays on and the machine hangs. If I bypass the scan, it accepts the various track allocations swap, u file system etc, attempts to creat the file systems, and the hangs. The following measures were taken to try and solve this disaster.. A: Various drive locations were used for the XENIX partition, including the entire drive, in the hope that there still may be some undetected damage on one of the Cylinders. The results were the same which ruled out any drive problem. B: The drive was initialized again with the old reliable WD1003 2:1, SPEEDSTORE and DOS were happy, XENIX died. C: Talked to SCO, they concluded I must have a bad Controller. D: Went back to WD1006 1:1 and the old reliable 2.2.1, same story. E: Talked to Western Digital and MIniscribe, discussing the reliability of the Speedstore software, both agreed there is no problem. F: Checked the memory, removed the extended 2 meg card removed all cards but the controller, reinstalled DOS, all was fine, tried to reinstall both releases of XENIX, same problem. G: Checked diagnostics speed, drive configuration, etc. Did some praying, and finally gave up. Any thoughts Post or Email, would be welcome..
