3-6 Disk Drives and Files
MX2 Reference Guide Revision A MX2A137REFGD
ORGANIZE.COM the utility for reorganizing flash disk data.
PM.COM the power-management utility.
REV.COM the utility that reports the firmware version.
UMBLINK.EXE the device driver for accessing upper memory
blocks.
VDISK.SYS the RAM-disk device driver.
XFER.EXE the serial-transfer utility.
The CONFIG.SYS file will load the FLASHDSK.SYS driver to create
the C drive and the VDISK.SYS driver to create the D drive. It will then
load DECODE.SYS and CFGDEV.SYS before chaining to its
counterpart on drive C. The AUTOEXEC.BAT file will chain to its
counterpart on drive C, except during a safe boot.
The purpose of the CONFIG.SAF file is to provide a minimal boot
configuration that preserves the flash and RAM drives. When the safe-
boot sequence is initiated, the CONFIG.SAF file is processed instead of
the CONFIG.SYS file. This prevents chaining into the drive-C
initialization files by omitting the NEWFILE = C:\CONFIG.SYS
command. It also eliminates the loading of the DECODE.SYS and
CFGDEV.SYS drivers.
