This driver is a firmware update for the Optima that enables V90 and ISDN.
The install disks that are supplied with the ISDN accessory kit fail when used with the later versions of this PC card when the firmware upgrade begins.
This Firmware was provided to me by Hayes UK to work around the problem. These drivers are not posted at the Hayes (or any other) site and (I believe) are for European versions of the card only.
To use 1) If available, attach the ISDN lead to the card before inserting the card into the laptop 2) Insert the card into the Laptop
3) Extract the ZIP file into a temp directory
4) Run setup and follow the prompts. If given the choice, opt for V90 instead of K56
5) Remove and re-insert the card.
Good luck. Jim.
