On the Connected Touch Pad, the Linux OS (based on Midoro-Linux) is placed on a 32MB CompactFlash. I could not find the way to enter the BIOS, but was able to get a Windows98 splash-screen, when I loaded (Win98) system files onto a CompactFlash and tried to boot from it.
Here is a pic of the board:
It does have an 44-pin IDE and a Floppy pinout. A laptop harddrive connected, spins up, but was not able to boot, because by default the BIOS is set to boot from the CompactFlash.
If anyone else has more info, please share......:)
