I have a Dell Optiplex 320 with a Pentium dual Dual Core CPU ( 2160). I am trying to boot off of a usb thumb drive with the disk images from the respective full DVD.isos. Both fail to get past probing the serial ports on boot. The i386 thumb drive has been used successfully to install a Dell 270. Currently both hyperthreading and speedstep are enabled. I have tried a few kernel parameters, such as pci=nomsi, acpi=off and noacpi to no avail. Has anyone succeeded in installing F8 on this hardware? regards, Alastair
