sorry for the long delay....
I received the patched BIOS, flashed it and ....
it worked!!
immediately after this I formatted and partionated the HD-took my old Celeron ~10 hours. that the reason why did not reply until now.
everything seems to work fine now [fingers crossed].
concerning the floppy- I just don't have one anymore. the one I had fell victim to a short circuit when I tried to plug/unplug it while the PC was running....:/
please have mercy, it was stupid, but afterwards I never thought of buying a new one. maybe I should...
anyway, thanks a lot for all the kind advice!
take care,
Sedenya
