How to get the internal SD card working

1. First of it all you need a working kernel 2.6 source.

2. Get the patches at http://mmc.drzeus.cx/wiki/Linux/Drivers/sdhci all the *.bin

3. Patch your Kernel

 cd /usr/src/linux
 patch -p1 < sdhci-0001.bin
 patch -p1 < pci-sdhc-0001.bin
 patch -p1 < mmc-respopcode-0001.bin

4. reconfigure your Kernel with menuconfig:

 make menuconfig

5. aktivate "Device Drivers" -> "MMC/SD Card support"

 <*> MMC support
 <*>   MMC block device driver
 <M>   Secure Digital Host Controller Interface support  (EXPERIMENTAL)

6. recompile your kernel & reboot

 make clean && make && make modules_install.. dont forget to copy your new kernel. ;)

7. Modprobe your new Kernelmodule:

 modprobe sdhci

8. Mount your SD CARD

 mount /dev/mmcblk0p1 /mnt

9. RocknRoll

Update for FC5 running the newest 2.6.17 kernel:

1. modprobe mmc_block

2. modprobe sdhci

Automated module loading

I'm using ASPLinux release 11 (Seliger) based on FC4 and kernel 2.6.17-1.2142asp.

• 1. Created the script /etc/sysconfig/modules/sd.modules to load modules on boot. Don't foget to chmod it 775.

#!/bin/sh
for i in mmc_core mmc_block sdhci; do
        modprobe $i >/dev/null 2>&1
done

• 2. It will be run after reboot. When you insert card the automount system in the KDE || Gnome will catch the medium on the fly.
