And one more thing for those brave... I have googled a little and found= a hack that should reroute the SD slot from FlashMedia to SD controlle= r. You can find the solution here: http://list.drzeus.cx/pipermail/sdhc= i-devel/2005-November/000036.html Pierre Ossman writes that: "SD/MMC control can be at _either_ the flash controller, or the SD host= , not both. The control for this is in a PCI register on the flash controller called MMC_SD_DIS and is documented as disabling MMC/S= D support in the flash media controller... the SD host controller takes= over at that point... A register in PCI space needs to be changed. A r= egister that is configured by the eeprom in the laptop. So how to do it then... First we need to know the current value of the reg. It is in subfunction 3 at offset 4C: 40: 00 00 00 00 01 00 02 7e 00 00 00 00 20 00 00 00 ^^ The bit we want to set is bit 2. So we change the above to 22. $ setpci -s 06.3 4c=3D0x22" This is obvisouly for Linux, but it should work on any system, except t= hat on FreeBSD one would use pciconf instead of setpci. Haven't tried m= yself just yet, but I will during the weekend.
