Just found this: http://freshmeat.net/projects/btmgr/?topic_id=139 Smart BootManager by suzhe - Saturday, April 1st 2000 05:29 EDT Smart BootManager is a tiny, powerful and multi-language boot manager written in assembler. SBM supports many features in only 30K bytes including multi-languages and themes, a user friendly menu system, partition auto scan, boot schedule, password protection, and more. SBM is the first GPLed boot manager to embed an IDE ATAPI CD-ROM driver, it can boot Win95/98/2K, Linux, FreeBSD, OpenBSD, and BeOS from CD-ROM. Multi-bootable image CDs are supported as well. ^^^^^^^^^^^^^^^^^^^^^^^^ John --- Matthew Franz <mf...@ci...> wrote: > If I recall ISOLINUX (vs. SYSLINUX) did not use El Torrito.
