the FORMAT.COM program, by displaying the File Manager (for
Windows), or by choosing the drive icon (for OS/2).
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
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 PCMCIA 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.
