Hello, Felipe. Thank you, Felipe, for suggesting that I use ROMBurst.c to extract the kernel and filesystem from Ospack. It gave me a good place to start researching.
It proved easier and probably faster to extract zImage from the Ospack of SharpROM 3.1 by using 'dd' in a terminal, rather than using ROMBurst.c or cutzrom.c, since I did not have a cross-compiler or on-board compiler installed. I was enlightened by 'crow' in a previous post at the OESF.org forum: http://www.oesf.org/forum/index.php?showtopic=7699&pid=46778&mode=thread&start=#entry46778 Also helpful was the documentation contained in Mark T. Grennan's cutzrom.c program source, which documented the organization of the 1.02 ROM for SL-5000. To confirm that the ZIMAGE and ROMDISK.BIN had not moved, I used the following terminal command after changing the working directory to be the same as the location of the Ospack file: dd if=Ospack | hexdump -C This command scrolled through the entire Ospack and at the end was a directory structure, which confirmed by comparison with Grennan's documentation, that ZIMAGE and ROMDISK.BIN had not moved since SharpROM version 1.02. Then, I adapted the advice of 'crow' from the OESF.org forum post mentioned above. In a terminal, To extract the kernel: dd bs=131072 skip=6 count=8 if=Ospack of=zImage To extract the file system: dd bs=131072 skip=14 count=128 if=Ospack of=initrd.bin I now have a 1 MB kernel (zImage) and a 15 MB file system (initrd.bin) So as not to clog everyone's mailboxes, I will send the 1 MB zImage file to you at your personal email address. Let me know if you want the 15 MB initrd.bin file. I can split it and send it to you in email attachment sized pieces, as I did previously with the 5500v31c.zip SharpROM. I will only send the 15 MB file system if you ask for it, so as to not clog your email unnecessarily. If anyone else wants these, let me know.
