Though the slot is MiniPCIe in form factor, it has been crippled to only accept devices with PCI-ID's contained in a BIOS whitelist consisting of the above list of devices (likely not exhaustive and varying depending on the particular system) with the additional requirement that they '''must carry the Lenovo brand name and consequently cost twice as much'''. If an unauthorized card is plugged in it gives a <tt>1802</tt> error on initial boot up before it even touches the operating system.

The BIOS is know to check PCI IDs (via whitelist) and block the boot process if it’s not satisfied (1802 error). The details vary. Above mentioned hardware might only be accepted if it comes with one set of possible IDs (for Lenovo). The same hardware (from the driver’s viewpoint) is often also available with other IDs if it is sold though other channels. (see also Problem with unauthorized MiniPCI network card, 1802 with MiniPCIe on t60,same).

Hacked BIOS with white list removed

Non-official patched versions of BIOS files are available for X300, X61, X61s, T61, T61p, R61, R61e (and others, i did it to x60s) which remove whitelist restrictions allowing non-lenovo PCI-e devices.. (see forum post: Ultimate R61/T61/X61/X300 BIOS (inc SATA-II)
