We first recommend for users and customers to get the latest BIOS update for these machines. Here are the issues encountered by our support group:

Toshiba Satellite Laptop models 2400-S201, 2415-S205, 1415-S 105 and most newer models: The reason the key is not found is because the Toshiba 2400-S201 comes default from the factory with parallel port not enabled. To enable the parallel port, go into the BIOS. On page I of the BIOS settings, verify the 'Parallel Port' is set to 'ECP'. On page 2 of the BIOS (which is actually where the fix occurs ), change the setting 'I/0 Parallel Port' from 'Not used' to 'LPT 1'. Toshiba Tectra 9100 Similar to the IBM Thinkpad machines, a hardware configuration needs to be applied via the BIOS for the parallel port. This change can be found on a second page in the BIOS regarding the parallel port. The actual configuration change is to "Enable" or "User Settings" from "OS Controlled" for the parallel port. This change then allows the port mode (ECP), port address (378), port memory (DMA 3) and IRQ (7) to be set for the parallel port to work with third party hardware devices such as the Sentinel SuperPro. Toshiba Satellite Pro 6000/6100 running Windows XP Pro Launch C:\Program. Files\Rainbow Technologies\Sentinel System Driver\SetupSysDriver.exe - Hit "Configure Driver" and make sure you see a physical address and port type for the parallel port --> If you don't see one, then the parallel port is not enabled! Follow instructions below to enable the parallel port. (please note that XP will still allow the printer to work even though the port is not enabled.) - Uninstall the Sentinel System Driver through Add/Remove Programs - Reboot and hold down the "ESC" key while tapping the F1 " button - Find the parallel port mode settings and enable it - Exit bios and reinstall Sentinel System Driver. A few other Toshiba laptops we've encountered exhibit serious issues in the BIOS; end-users and customers should contact Toshiba to get the latest BIOS update for that model of laptop.
