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 ATA Card Mount Utility, install the PC Card storage API device driver (PCMSSDIF.SYS) for OS/2. Formatting 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 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 ATA Card Mount utility to assign a drive letter to it. Storage Card Device Manager OS2PCARD.DMD is the device manager for the 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 PC Card Storage API Device Driver for OS/2 This device driver provides a communication function between PC Card Director or the mount utility and the ATA card device driver for Chapter 5.
