Let it be known for the record that he, who wants to boot from an fla device (DiskOnChip) muat write all of the following as the first thing on the medium: 1.) boot loader 2.) kernel 3.) root mfs (if applicable) This is necessary because the BIOS can't load anything that is beyond this mark of 2 MB (or may be more or less than 2 MB.) This is a FAQ ... may be it should be described in the fla driver documentation. regards -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow@regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistent Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
