Sorry, what I was getting at was that a bad bios (eg latest could have introduced a regression) can cause the symptoms you are seeing. The bios change sure seemed to fix my problem. In the mean time, try dmidecode to extract some of the versions of the BIOS and hardware you are using. Perhaps it might tweak someone's memory to a similar problem as yours. ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
