Hello,
I'm trying to boot a Linux system that has the following configuration: - 32MB of Flash (IDE Flash Drive), where a kernel image and a compressed root filesystem image are stored. - 256MB of RAM, 128MB of which will be used as a RAMDisk (believe me, this is cheaper than 128MB Flash + 128MB RAM ... :).
After looking for information on how to do that on the 'Net and in the Documentation/ directory of the kernel src, I've been able make the Flash Drive bootable. Unfortunately, it's bootable, but it doesn't boot successfully ... :(
What I tried: - Compressed the image I used to boot the system from a regular IDE HD to a file called rd_image.gz (~20MB compressed), and copied it to the IDE Flash Drive. - Compiled a 2.4.6 kernel with RAMDisk and initrd support built-in, and then copied it to the IDE Flash Drive. - Ran LILO with the following config. file (based on the doc. I found so far):
boot=/dev/hda # The FlashDrive device install=/boot/boot.b map=/boot/map append="ramdisk_size=131072 initrd=rd_image.gz" vga=normal default=Linux delay=5 image=/boot/vmlinuz initrd=/boot/rd_image.gz root=/dev/ram0 label=Linux read-only
LILO completes the operation without problems (no errors). However, when I boot the system from the FlashDrive, this is the output I get:
LILO Loading Linux ...................................................... ..............................................
That's it!! The system hangs at this point (it really hangs, to the point that the "soft" power on/off doesn't work anymore, and I have to turn off the system from the back in order to reboot it).
What am I doing wrong?? Is my RAMDisk image too big (I thought there was no limit, as long as you had enough RAM ...)?? Does anyone here know a good resource on the 'Net where I can find more detailed information about creating a RAMDisk-based Linux system that boots from a device other than a floppy disk?? Most of the docs I found were related to boot / rescue / utility floppies, so I don't know whether this is the right way to do it or not ...
Any help would be appreciated.
Later, Ivan
