What types of peripherals can I use in the Mini-PCIe slot on the bottom of my Eee?
The full answer to this question isn’t yet known because there aren’t many Mini-PCIe devices on sale and the few people have experimented with their Eees. Inserting a card into the Mini-PCIe slot will disable the onboard SSD-drive and the system expect to find a boot device in the slot. To work around this behavior, 3.3v power has to be routed from another spot on the motherboard. On Asus Eee PC 8G 702 models the SSD is a Asus Mini-PCIe card that’s mounted on the slot in the expansion bay (pictures). Other uses, when the trigger issue is fixed, are: 802.11b/g/n wireless cards, HSDPA/3G/EDGE/GPRS modem cards, and Solid State Disk cards. The warranty sticker on the expansion bay is not legally binding in many countries and Asus has recently stated that it is OK to remove the sticker. Forum user tristand has determined a way to add standard USB devices to the MiniPCIe slot. This upgrade requires soldering – it is recommended only for advanced users.
