Dear SCO Customer,

Support Level Supplement (SLS) PTF7082A, the UnixWare 7.0.1 psm_time Driver
Patch, addresses a problem where the system cannot read the second boot
floppy. Upon inserting the floppy, the system returns this message: 

           Error determining if this is the correct diskette

           Warning: FDC unexpected state

The problem occurs because the psm software is too strict with timing speed
sanity checking limits.  If a machine is more than twenty times faster than 
the reference CPU, then the operating system prints a warning and sets the 
calibration to the sanity limited value.

SLS PTF7082A relaxes timing speed sanity checking limits to allow for faster
machines.

SLS PTF7082A contains this file: 

        /etc/conf/pack.d/psm_time/Driver.o
