Working from the console (ie no X or KDE to interfere), using dd if=/dev/acd0c of=file.iso bs=2048 the dreaded "microuptime going backwards" began in earnest. As the source CD had only a small dta footprint, I let it run. As the iso file nearde the end, the MUT messages slowed, and on completion they were quite gentle. I still had to reboot, of course. The ISO file was just file, and I burned it using burncd without incident. using mkisofs -o imagefile.iso /dev/acd0c on the next disk passed without incident and was stored and burned successfully. Why should dd start MUT and mkisofs not do so? Does this help anyone solve the problem? Yes I DO have an Athlon CPU and a VIA chipset MB -- Regards, Brian To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
