Hi i tried ahci_drv.run ,it worked well when i tried to use ahci_drv and part_blk making l4linux access to hard disk, it failed.

If you want to see the partition table in L4Linux, please omit part_blk and let L4Linux access the AHCI driver directly. What part_blk does is, it exposes a 'single' partition as a block device to L4Linux and on a partition there are no other partitions. It seems that is not what you want to achieve.

Hi Sebastian, Thank you for your explanation. I omit part_blk and get the partition table of my hard disk. But the L4linux can not use the hard disk.I mean use fdisk command in l4linux just find no device,so I can not mount any partition of my hard disk. At first I think I should change some config of l4linux,but I am not sure whether it is the point.

I guess the issue is, that the device nodes for the partitions must be created first. Check for the major number of '/dev/sda' (in L4Linux), which should give you something like this:
brw-r--r-- 1 root root 254, 0 Jul 24 2012 sda
Here the major number of 'sda' is 254. For each partition you now need to create a device node with a different minor number. Minor numbers 1 through 4 symbolize primary partitions, while number 5 to X mean logical partitions.
Example creating a device node for the first primary partition:
mknod /dev/sda1 b 254 1
You should now be able to mount sda1.

Sebastian
