PC Cards
Your computer has two PC Card slots.
These slots conform to the PC Card Standard; therefore, communications or SCSI devices,
etc., may be utilized.
Type I (3.3 mm) or II (5.0 mm):
Two cards can be used simultaneously.
Type III (10.5 mm):
One card can be used only in the slot 1.
CAUTION
Check the PC Cards' specifications. Be sure the total operating current does not
exceed the specified limit. Damage may result otherwise.
Allowable Current: 3.3 V: 400 mA, 5 V: 400 mA
There are times when both a Type I card and a Type II card will not work at the same
time.
ZV card, SRAM card, FLASH ROM card (except for an ATA interface) and card
requiring 12V are not supported.
With the repeated insertion/removal of a PC Card, the computer may no longer
recognize the PC Card (depending on the type of card). In such cases, restart the
computer.
When inserting one more CardBus type card with one already inserted, after entering
either the standby or hibernation mode, the computer may not function properly.
If the computer freezes after resuming from the standby or hibernation mode, try
removing and then reinserting the PC Card. If this does not correct the problem,
restart the computer.
NOTE
Before connecting a PC Card, change the multimedia pocket device in accordance
with the media in which the driver of PC Card exists. Once a screen to install a driver
is displayed, the multimedia pocket device cannot be recognized even if it is properly
installed.
