Advanced Information for PC Cards
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 the drive letter to it.
Parameters for the OS/2 PCMCIA ATA Card Device Driver
OS/2
The following are the parameters in the OS/2 PCMCIA ATA card device
driver and their explanations:
BASEDEV=PCM2ATA.ADD [/S:n] [/P:hhhh] [/EXIRQ:n]
[/NOBEEP] [/B] [/STBTIME:n] [/MDRV:n] [/!DM]
/S:
n
Specifies the number of PC Card slots. /S:1 shows that
there is only one PC Card slot. When this parameter is not
set, the number of PC Card slots is set to 2.
/P:
hhhh
Specifies the lower limit for the I/O address of the ATA
card. The device driver assigns the next usable I/O
address from this lower limit to the card. When this
parameter is not set, the device driver looks for a usable
address and assigns it to the card.
/EXIRQ:
n
Specifies the IRQ level that
is not
assigned to the card.
You can set more than one IRQ level.
/NOBEEP Specifies not to beep when a storage card is installed.
When this parameter is not set, you will hear a beep every
time a storage card is installed into the PC Card slot.
/B Specifies that OS/2 has started from an ATA card. When
this parameter is set, there will be no redundancy in
assigning the logical drive to the slot where OS/2 was
booted. It depends on the ATA card whether you can start
OS/2 from it.
/STBTIME:
n
Specifies the time (from 1 to 21 minutes) until entering
standby mode. When the ATA card is not accessed for the
time specified by this parameter, the ATA card enters
standby mode (only when your ATA card supports standby
mode). When this parameter is not specified, standby
mode for the ATA card is disabled.
/MDRV:
n
Specifies the number of extra drives that can be used in
addition to the number of PC Card slots available for the
PCMCIA storage devices. When this parameter is not
