Hi guys, I tried this solution with a USB KEY and it doesn't work at all ! It's weird because the USB KEY use exactly the same principle. 1) - Get the USB\VID adress : With Devcon I list all the " hardware ID's of devices. " with the command line : Devcon /hwids * > OUT.TXT #-----------------------------------------------------# USB\VID_0930&PID_6540F8125605192D91E Name: USB Mass Storage Device Hardware ID's: USB\Vid_0930&Pid_6540&Rev_0200 USB\Vid_0930&Pid_6540 #-----------------------------------------------------# 2) - Add the new ID within the " txtsetup.oem " #--The following lines give additional USB floppy support id = "USB\VID_03F0&PID_2001", "usbstor" #--HP id = "USB\VID_054C&PID_002C", "usbstor" #--Sony id = "USB\VID_057B&PID_0001", "usbstor" #--Y-E Data id = "USB\VID_0409&PID_0040", "usbstor" #--NEC id = "USB\VID_0424&PID_0FDC", "usbstor" #--SMSC id = "USB\VID_08BD&PID_1100", "usbstor" #--Iomega id = "USB\VID_055D&PID_2020", "usbstor" #--Samsung id = "USB\Vid_0930&Pid_6540", "usbstor" #--MY USB KEY * 3) - Go to the BIOS configuration and enable the floppy emulation over the USB KEY On theory everything is fine, except the fact that it doesn't work , any ideas ?
