It's not possible to "revive" the BIOS after the machine has booted. The BIOS (and DOS) doesn't work that way. > because if I plug in a USB drive (Fat32) after Freedos booting, the > letter is not attributed, i can't access content. > if i plug USB drive before Freedos booting, i can access USB content > with a letter (d:) There's no way to fix that, at least not directly. Some BIOSes do support "plug and play" in a limited way. That is, after booting, they will allow you to plug and unplug the USB drive from the slot, and some BIOSes may even allow you to insert different USB drives into the slot. But, you still must have a USB drive plugged in when you're booting or DOS won't assign usable drive letter(s). And, not all BIOSes support even this minimal level of "plug and play". > i already use "dos usb driver", this crash my PC, Which DOS USB Driver is that?

As you stated above, though, this only works when you have the USB drive plugged in while booting. So, you do actually need drivers to have it work like you want it to. You can try my USB drivers (available at http://bretjohnson.us), which do support plug-and-play like you're wanting. AFAIK, my drivers are the only ones that do. However, the current version of the drivers only work with a limited subset of USB hardware (UHCI USB host controllers, which are manufactured by Intel and Via). Since your computer is new, it may not have the right kind of hardware. I'm working on an updated version of the drivers, but I have very little time to devote so it's a slow process. ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
