I don't know why you are fretting about this prompt and momentarily pause in the boot process. Also think you are confused about the MBR thing on the 2nd drive. The prompt above is coming from your first HD. If the BIOS did not know about the 2nd drive the F5 entry would not be there and the FreeBSD F1 entry would still be there. You could hide this prompt by retuning the MBR to pause 0 or 1 seconds. Zero might be infinite. To eliminate the prompt, wipe the HD and reinstall "dangerously dedicated." The result will be a disk which lacks the headers which allows other x86 OS's to understand what/how the disk is used. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
