Altos 580 and CP/M-MP/M Again.

What, exactly, do you mean by "partitioning and making a filesystem?"

Are you sure you've used the correct sector size and number of sectors per
track? The only Altos 580 I've dealt with had a Quantum 540. It's possible
that the firmware won't support a 6-head drive.

I tried a functional CMI 40-MB drive and, though it worked in a CP/M box
BEFORE it was in that system, it didn't work there, and, when I removed it and
put it back in the system whence it came, it didn't work there any longer
either. I wouldn't blame the Altos box for that, but, who knows?
