SD Card slot
PCI-based SD Card slot
This implementation is called "SD Card with IO support", and supports in addition to regular SD memory cards also special SDIO cards (e.g. Bluetooth, WiFi, etc).
lspci reports it as a Ricoh device with PCI ID 1180:0822 (X Series, Z60m, Z60t), or 1180:0841 (Z Series).
The sdhci project has developed a driver that supports these and other SD controller chips. The driver has been reported to work on ThinkPad X40, X41, Z60m, Z60t, X60 and X61 models, and has been available in mainline kernel since 2.6.17-rc1. See also "How to get the internal SD-CARD working".
It works with SDHC cards too (at least on my X41 Tablet and linux 184.108.40.206).
Models featuring this Technology
- ThinkPad X40, X41, X41 Tablet
- ThinkPad X60, X60s, X60 Tablet, X61, X61s, X61 Tablet
- ThinkPad Z60m, Z60t
USB based SD Card slot
This implementation only supports SD Memory cards.
Should be supported by the Linux USB Storage drivers (usb-storage).
