Card Identification (CARDID.EXE)
This client device driver detects the insertion and removal of PC cards, automatically determines the
card type upon insertion, and then configures the card and slot/adaptor (if it is an I/O Card).
SRAM Card Driver (MTSRAM.EXE)
This SystemSoft device driver recognizes and supports SRAM cards.
IDE/ATA Support (ATADRV.EXE)
ATADRV.EXE is a block device driver that supports ATA Type II Flash Disk or ATA Type III
hard disk PC cards.
Option
/S:x
Specifies if ATADRV is to be run in slave mode. The MTD Driver (MTDDRV) is the only master
control driver currently available. Installs the ATADRV device driver as a slave(/S:x) to MTDDRV.
It also specifies the number of devices (1 to 8) it can support. A value of 0 can also be used with /D
or /S. When a value of 0 is used, only the mode that was specified (/D or /S) is implemented, not the
number of devices assigned during installation or specified using the CONFIG utility. When this
/S switch is used, ATADRV must be installed in CONFIG.SYS before MTDDRV and both
ATADRV and MTDDRV must be installed before CARDID. Refer to ATA Driver Modes section
which follows.
Option
/D:x
Specifies the number of drives that the system supports when installed either as a block device driver
or as a slave device driver. Installs the ATADRV device driver as a block device driver (/D:x).
It also specifies the number of drives (1 to 8) it can support. A value of 0 can also be used with /D or
/S. When a value of 0 is used, only the mode that was specified (/D or /S) is implemented, not the
number of drives assigned during installation or specified using the CONFIG utility. When the /D
switch is used, ATADRV must be installed in CONFIG.SYS before CARDID.
Safe mode
Range: 0 to 8 (Default: 2)
