PCMCIA Problem with Dell Latitude LX4xxxD

Return to The Warp Pharmacy:Hardware

Last update: 7th February, 1996

Symptoms
The PCMCIA drivers supplied with OS/2 Warp fail to configure PCMCIA cards correctly on a Dell Latitude LX4100D; A cold boot results in the socket services driver (PCMCIA.SYS) showing a Trap 000e, a warm boot will allow the drivers to load correctly, but the auto-configurator will incorrectly identify any cards that are present. (e.g. a modem will appear to be a memory card.)

Hardware
The problem occurs with Dell Latitude LX4100D and LX475D Laptops with a flash BIOS revision earlier than A02

Problem
The flash BIOS in less recent LX's does not support plug and play PCMCIA.

Procedure
Upgrading the flash BIOS to level A02 will cure all; The BIOS upgrade can be obtained from Dell via their WWW and FTP sites; The file LATLXA02.EXE is a self-extracting archive that contains the BIOS upgrade program and instructions on how to use it.

URL's for the file are (note case!):
