|Apparently your laptop is pretty old. Why do you feel you need a BIOS update? What do you expect to gain? The last BIOS available is R0247U0 dated 6/14/2004, here's what it "fixes":|
■ Resolves the issue where, after installing the Microsoft® Windows® operating system XP Service Pack 1, the computer hangs when a USB 2.0 hard drive is connected via an NEC® USB 2.0 PCMCIA PC card.
■ Improves stability after resume from the Standby mode.
The BIOS file & instructions are at the SONY website. The update is performed from Windows, not from DOS (floppy).
