[net.micro.cpm] Otrona Attache warmboot anomaly?

bridger@rand-unix.ARPA (Bridger Mitchell) (03/13/85)

The Otrona Attache running cp/m 2.2.3 or 2.2.5 appears to
handle warm-boots in some non-standard way.  When the bios warm-boot
jump is intercepted, diverted to a resident system extension module
that loads the C register with the logged-in drive from (0004)
and jumps to the CCP entry, the system hangs.

Does someone have the bios code, other experience, or a CURRENT
contact for technical info?

Thanks.
