I have a SL-5500 with a broken CF slot. It recognizes my WiFi card but it doesn't recognize my 128MB CF card, I've ran the tests in the diagnostics menu and they report 4 errors.
So I guess updating via CF is out.
However, I have OZ 3.5.4 running, so I'm wondering... Is it possible to flash the Z from the commandline?
Copy the required files to sd
dd the initrd.bin file to /dev/mtdblock4
and the kernel file to the appropriate block?
Can anyone help?
