The following reply was made to PR amd64/111955; it has been noted by GNATS. From: Bob Johnson <bob89@eng.ufl.edu> To: bug-followup@freebsd.org, Eamon Roque <Roque@itg.uni-muenchen.de> Cc: Subject: Re: amd64/111955: [install] Install CD boot panic due to missing BIOS smap on 5.5 through to 7.0-Current Snapshot 200704 Date: Fri, 7 Mar 2008 17:48:41 -0500 "FreeBSD only calls the BIOS SMAP call from virtual 86 mode both in the loader and in the i386 kernel. The fix is quite complicated and involves rewriting the boot code to invoke BIOS calls from real mode rather than virtual 86 mode." ?? but FreeBSD i386 boots and runs fine on an HP dc7700 that gives the "No BIOS SMAP" error when booting AMD64. I'm completely ignorant of the boot process for AMD64, but could code be lifted from i386 and moved to AMD64 to solve this?
