/ E MS When this parameter is specified, the device driver uses
the EMS resources if they are usable. When this
parameter is not specified, the device driver does not use
the EMS resources.
/ T SIZE: n
You can specify the size of the table for the device driver
data in the resident memory area. When the EMS
resources are not usable, the data tables are created in the
resident memory area. When the EMS resources are
usable, this parameter is ignored. The table size depends
on the variable n and is calculated as follows:
Specify n in a decimal number. When this parameter is not
specified, the device driver creates the table with n =4.
Select the variable n depending on the total capacity of the
Flash card. The following is an example of the relationship
between the variable n and the total capacity of the Flash
card:
OS2PCARD.DMD is the device manager for the PCMCIA storage card.
O S / 2
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 ( O S2DASD.DMD); however, under some conditions the format will
not be 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
table size = n × 1024 bytes
Up to 10MB: n =4
Up to 20MB: n =6
Up to 40MB: n =10
