Just to let you all know that this LPT cross-wired cable worked like a charm on this model of LapTop! :))))))))
So the BIOS password was removed automatically just by powering-on of the LapTop with described cross-wired cable.
But now I've run into another kind of a problem:
it seems that the built-in CD rom does not work
(it won't load any bootable Windows CD) and I'm wondering is this Tecra model of LapTop capable of booting from a USB port?
