I have an external hard drive that caused one of my PCs (plain vanilla HP machine) to cogitate for almost 5 minutes on every boot, eventually coming to life. Unplugged it and got a normal boot. Different PC (plan vanilla COMPAQ - duh, HP too!) boots fine with the external drive. That said, I have a handful of USB to serial gizmos, both Prolific and FTDI based that work OK on all of my PCs - HP, COMPAQ and a number of 'homebrew' types with various manufacturer MBs. I suspect the root of the evil is in the PC BIOS. 73, Bill N2BC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
