Storage Card Device Driver 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 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 OS/2 PCMCIA Storage API Device Driver This device driver provides a communication function between PC Card Director or the mount utility and the OS/2 PCMCIA ATA card device driver. As a result, a utility in the upper layer can get the drive letter or partition information for the PCMCIA storage card. The following is a line from the CONFIG.SYS file that describes the Storage API device driver: DEVICE =[drive:][directory]PCMSSDIF.SYS Flash Card Memory Technology Driver This device driver is used to read and write to a Flash card. It is used by OS/2 Flash card driver (PCM2FLSH.SYS). The following is a line from the CONFIG.SYS file that describes the Flash Card Memory Technology driver, according to the operating system: For OS/2: DEVICE =[drive:] [directory] FLSH2MTD.SYS (↑Memory Technology driver) DEVICE =[drive:] [directory] PCM2FLSH.SYS (↑Storage card device driver) 190 IBM ThinkPad 380 or 380D User's Guide
