Question
initrd script - booting Linux from SDHC Card
Hi everyone,
I have a netbook computer with an internal solid state drive that Slackware 12.2 picks up as HDA.
I have the drive partitioned into the following partitions:
HDA1 - NTFS - Windows XP Partition
HDA2 - EXT3 - Linux BOOT Partition
And I have an internal SDHC card reader. If I load these modules with modprobe or insmod (mmc_core, sdhci, sdhci-pci, mmc_block) and if I make nodes as follows in Linux:
mknod /dev/mmcblk0 b 179 0
mknod /dev/mmcblk0p1 b 179 1
I can mount and use the SD card by mounting /dev/mmcblk0p1 to a folder, say, /mnt/mmc
I have created an INITRD.GZ file that contains the modules needed to detect the MMC card, and updated my lilo.conf accordingly so that the INITRD.GZ file is used, but it still won't boot a slackware 12.2 installation I installed on /dev/mmcblk0p1 .
I'm thinking that if somehow, during bootup, after the SD modules have been loaded from INITRD.GZ, I can somehow have a script run before lilo attempts to boot from /dev/mmcblk0p1 (which it probably doesn't see) to execute the mknod commands shown above. Basically, this whole project is for the sake of having XP mainly on my solid state drive, and Slackware Linux on my SDHC card. Any help is appreciated.
Thank you all in advance.
