I am ready to throw this NB250 in the bin but I need it and XP for our navigation software, AIS and a serial port adaptor for Garmin GPS. After 20 attempts I did enter BIOS on start up and reset the settings. I still have the same start up issues being I get as far as the Toshiba/Intel page. Before the BIOS entry I did fit the old memory module and it made no difference.
That said, we don’t know if the old module is damaged but it did work and boot up sometimes. The only other hint I have is it seems to start up ok the first thing every morning, (after sitting idle for 12 hrs plus). Then every other attempted start fails until the next morning.
