Creating a INITRD image for the ELF can be done using the following as a guide: #cd /tmp #mkdir ram #dd if=/dev/zero of=ramdisk bs=1k count=4096 #mke2fs -Fvm0 ramdisk 4096 #mount -o loop ramdisk /tmp/ram #cp -a /rootfs/* /tmp/ram #umount /tmp/ram #dd if=ramdisk bs=1k count=4096 | gzip -v9 ramdisk.bin once the ramdisk.bin file is created you can use the FMU.axf program to transfer the INITRD image to flash. store the image at block #16 and name the entry INITRD. currently there is a problem transfering the INITRD from the pcmcia slot, so you will have to transfer this via the serial port NOTE: you should have built a root file system in the directory /rootfs . if you do not have one already built you can use the root fs from the tuxscreen web page or use the tar ball from the www.small-linux.com pages ( www.abcsinc.com/small-linux )
