Utilities (T 74 and T 76)
This chapter describes the two new utilities available on the VAXstation
3100 models 38 and 48 systems. These two utilities are both used to
format RX23 diskettes. Test 74 formats the special diagnostic key on the
test diskette, which allows the field service system exerciser to perform
writes to the drive. Test 76 formats new diskettes for normal data storage.
Table 3–1 lists all of the utilities available on the VAXstation 3100 models
38 and 48 systems. Refer to the VAXstation 3100 Maintenance Guide for
a description of these other utilities.
