Precision M70 LOCKUP when inserting Parallel Port PCMCIA card (SUNIX CBP0020) - REPOST

When trying to insert the above mentioned PCMCIA 32-bit Parallel Port card, the Precision M70 laptop (Win2k, SP4, all other applicable MS updates, all latest Dell M70 drivers) completely locks up.  The OS also does not attempt to find the card.

 

If the card remains in the socket, CTRL-ALT-DEL and CTRL-SHIFT-ESC do absolutely nothing - the only possibility is to power down the laptop.  However, if you eject the card while locked up, the laptop immediately continues to run correctly with seemingly no adverse effects.

 

The M70 PC card slot is functioning because I have installed PC cards from SocketCom (Dual Serial socket cards) and it does properly run/support them.

 

Also, the above SUNIX Parallel Port socket card, CBP0020, does work in a Dell Latitude D610.  However, it refuses to work in the M70.  The description of the card is that it is Card Bus compatible, 32-bit, Win2k and XP compatible using the parallel chipset SUN1888 (compatible with ACC3203, ST-78C36, HT6535).

 

The D610 appears to have the same Texas Instruments PCI Cardbus Controller.  The only difference in the specs being that the PC card in the M70 stest that its PC Card connector size is 80 pins (???) while the D610 is 68 pins.  However, the M70 does support the SocketCom cards which are 68 pin SocketCom Serial cards, so why not the 68 pin SUNIX Parallel socket card?

 

The cardbus controller drivers are the same on both machines (6/19/2003 - 5.0.2195.6717).

 

There was an earlier message on this forum concerning problems with a SATA socket card which had similar symptons when plugged in (laptop lockup).  However, there was no real solution to their problem (reinstall drivers).

 

Does anyone have any idea why this parallel PCMCIA will not work in an M70 but does work in the a D610?
