File, Drive, and PC Card Problems

If a PC card doesn’t work properly in a card slot

For information about compatible cards, visit our Web site at

http://www.hp.com/go/omnibook. Or contact Hewlett-Packard as described in the

Support and Service booklet or in OmniBook Support in the online OmniBook

Library.

• Try removing and reinserting the card.

• Try inserting the card in the other card slot to check the connector.

• Try removing a PC card from the other card slot, if another card is present.

• For a data storage card, check that you’re using the correct drive letter.

• If a data storage card doesn’t work properly, check if it has a write-protect switch

and that it is set properly.

• Shut down Windows, then reset the OmniBook.

If the OmniBook doesn’t reboot successfully from drive A

• If the OmniBook can’t reboot from drive A, use the System Configuration Utility

to check that the floppy drive is the first boot device.

If drive C has problems

• Insert the Support Utility floppy disk in the floppy drive, then press

CTRL+ALT+DEL to reboot from drive A. You can use commands on the floppy

disk to check and possibly repair drive C.

If a backup-tape drive does not work correctly

• Its bus speed might be too slow for the OmniBook. You can decrease the

OmniBook’s bus speed by pressing FN+MINUS. (To restore the normal speed,

press FN+PLUS.)

Floppy disks and PC disks are removable disks.

• If you have used Microsoft DriveSpace compression to compress drive C and

you want to use compressed removable disks, you must turn off 32-bit file

access for reliable operation. In Control Panel, use the Enhanced icon, then

choose Virtual Memory and Change. (Drive C compression, removable-disk

compression, and 32-bit file access should not be active at the same time.)

• If you want to use Microsoft DriveSpace compression on removable disks

without compressing drive C, use the following steps:
