PROBLEM: (80541) (PATCH ID: OSF510-058)
********
Compaq has determined in laboratory testing that there is a theoretical 
possibility that during read and write operations to the floppy disk on
DS10, DS10L and ES40 AlphaServers and XP900 AlphaStations, a
single byte of data may be inaccurately read or written without notice
to the user or system.  The potential for this anomaly exists only if
floppy data read and write operations are attempted while there is
extremely heavy traffic on these Alpha systems' internal input/output
busses.  Although Compaq has observed the anomaly only in laboratory
tests designed to create atypical system stresses, including almost 
constant use of the floppy disk drive, we are supplying this patch to
address this potential issue.
