Any PC Card installed in the slot is recognized by its device driver,
so regardless of its type, you can access the card by the drive name
assigned to the slot.
Notes
Install PCM2ATA.ADD for all storage cards, even if you are
using SRAM or Flash cards.
If using the PCMCIA ATA Card Mount Utility, install the
PCMCIA Storage API device driver (PCMSSDIF.SYS) for
OS/2.
Formatting PCMCIA Storage Cards before Use
You need to format new PCMCIA storage cards before using them.
For Flash cards, run the Flash Format Utility (FFORMAT2.EXE); then
format the Flash card.
For ATA cards and SRAM cards, there is no
need to run any programs before formatting the card.
To format the card, use the FORMAT.COM program by choosing the
drive icon.
Using PCMCIA ATA Cards with Multiple Partitions
The device driver assigns a drive letter only to the active (bootable)
partition of the ATA card if it holds multiple partitions.
For other
primary partitions or logical drives in an extended partition, use the
PCMCIA ATA Card Mount utility to assign a drive letter to it.
PCMCIA Storage Card Device Manager
OS2PCARD.DMD is the device manager for the PCMCIA storage
card.
Specify the /!DM parameter in the PCM2ATA.ADD line, so that
OS2PCARD.DMD is used instead of OS2DASD.DMD.
If you do not
specify /!DM, PCM2ATA.ADD uses the OS/2 standard Storage Card
Device Manager (OS2DASD.DMD); however, under some conditions
the format is not correct when you use OS2DASD.DMD.
The following is a line from the CONFIG.SYS file that describes the
Storage Card Device Manager:
BASEDEV=OS2PCARD.DMD
