"Windows(r) 2000 only. Revision 2.01 for the Tazer motherboard. This BIOS is identical to the 2.00 BIOS except the USB keyboard support option has been added and set to disabled. This change was necessary to prevent power management issues under Windows 2000. There is no need to update your system to this BIOS if you run Windows 98 or Windows NT 4. This disk image will create a bootable BIOS flash disk. (Will work with LS120 drives.) The files contained in this Bios utility are the same as the "Tazer201.exe" Bios utility."
