Installing and Configuring Enhanced OS-9
Enhanced OS-9 for X86 PCAT 135
0xe800105c [ffffffff] SCRATCHB
The show dsp option displays the current Symbios scripts location; it is
useful when and if the SCSI bus locks. The information obtained will
help to deal with drives that appear to have problems. If a SCSI drive
appears to hang, you can load the ’Symbios_info’ utility and run it after
the hang to see the state of the scripts. Tech support can use this
information to determine what the drive is doing or not doing. The
section of the dump shown may be compared to the ’v53c810.lst’ file.
