This has nothing to do with disklabel. It has to do with FreeBSD reiniting the IDE drive with a geometry other than the BIOS geometry, for no good reason. > This installation was really time consuming and it shows there is some > potential to improve fdisk, disklabel and sysinstall.

Agreed. On the other hand, a DOS install will occasionally install a boot-sector loaded TSR to supply LBA support to a system that does not already have LBA support, by hooking INT 13 and driving it that way. It's very helpful for future work if LBA support is in there somehow -- and we don't have an LBA boot-sector TSR to replace the DOS installed one in those cases.
