Bret's USB drivers in DOS so far are written specificly for UHCI, an USB 1.1 implementation. Other vendor-provided (usually product-related) and commercial implementations exist that go beyond UHCI, one such can be found at [ http://www.georgpotthast.de/usb/ ]. Loading USB drivers from a floppydisk inside an USB floppydrive will likely cause a system crash though, as these USB drivers tend to hijack the entire USB stack, disconnecting you from any and all previous USB devices and their contents (either at per-controller basis or all USB-controllers at the same time). One workaround is a ramdisk loaded by floppydisk, but that's pretty nasty to setup properly: * create ramdisk * find driveletter for it * copy shell * copy batchfile * copy usb drivers * switch to ramdisk * execute copied batchfile * don't access A: anymore till reset The Syslinux/memdisk method is slightly easier as the ramdisk created by MEMDISK will then be drive A:. Guess I should be creating such a disk soon. Bernd ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
