hey sorry for the delay in replying with the solution.
well i resolved the prob, n my computer is working fine.
the prob was that my computer has a card reader, and the printer that i was trying to install also has a card reader, so there was a conflict betweeen these 2. wen i put the USB emulation to NO BOOT in BIOS, the prob got resolved.
but there was nothing to do with the floppy cables or any other drive as thought previously.
any way thanks for all that suggestions and iam sure that i wil b a regular visitor to this forum to put in my questions and to answer others issues if i know the resolution for that.
