|Unfortunately, the bios version you currently have cannot boot from anything but the 16 MB internal Sandisk. |
The only other work-around involves the Sandisk's QNX operating system, and re-flashing the bios while booted in QNX.
This would involve connecting to another machine (using the IOpener's modem) which has the necessary bios file stored on it.
Do a search on this forum for "QNX bios flash", and see if the files needed, are still around somewhere.
"Removing the goop method" may or may not work, due to the poor quality of the bios chip socket. The socket may also require replacment, in addition to the bios chip itself. Good luck!
