Okay,
So good news/bad news:
Good news: Setting the jumpers per your fax's recommendations I've got the drive up and running. I still need to use the BIOS from the CCIV but w/ the drive jumpered as above and BIOS enabled the drive becomes accessible. A couple of observations:
1. The Everex LCD panel is still disabled since the BIOS routines are replaced w/ the ones from the CCIV.
2. The M2-ABIOS still recognizes the drive as 1.44 and will not work with the drive properly. However, setting the drive to 2.88 manually in config.sys allows for similar behavior to the CCIV BIOS.
Bad News: Lots of weird incompatibilities. For example formatting an ED diskette using format a: produces the correct format. The format is completed and the disk is perfectly usable. However, if I was to format the same disk using format a: /s I get a report at the end indicating over 4 GIGABYTES of bad sectors (even though the free space on the disk is correct). This is not limited to ED disks as a std 720KB disk produced the same result and the same error. These disks will not boot - indicating that the command processor is missing if you attempt to boot from them. However, formatting the same disk and ten transferring system files using the "sys" command produces a perfectly good disk which boots properly. The same behavior was noted w/ 2M-ABIOS loaded both w/ and w/o CCIV BIOS enabled.
Dir, copy, move, etc. commands seem to work fine on the formatted disk. So what am i missing? Is this a shortcoming of DOS format or do I need to use driveparm or driver.sys?
As always thanks for the help Chuck!
