perhaps the boot-from-cdrom code in Smart Boot Manager? Bernd>>>No, since booting from CD-ROM requires that the El Torito part of the BIOS is activated, which it won't be if it didn't boot from CD-ROM in the first place. ---------------------------------------------------------------- Op deze e-mail zijn de volgende voorwaarden van toepassing: http://www.fontys.nl/disclaimer The above disclaimer applies to this e-mail message. ----------------------------------------------------------------
HPA, There's a COMBOOT module made out of Smart Boot Manager. The SBM -> CBT diff has been done by Jeremy Davis for the FreeDOS project (because we have a not so stable opensource DOS cdromdriver called ATAPICDD, also written by him, and this way we can let even 386 systems boot from cdrom, although the eltorito standard was introduced later, in 1995) http://fdos.org/bootdisks/autogen/btmgr-3.7-1.cbt.zip If anyone manages to extract the cdrom-booting part out of this Smart Boot Manager, be my guest. I don't need a full boot manager, just the eltorito stack for onboard ATA Smart Boot Manager seems to exist of multiple modules: 1) Installer (sbm.exe for example for win/dos, which writes payload to diskette) 2) Payload (sbm.bin) 2a) Menu 2b) SBM engine 2c) hardware interfaces Bernd ---------------------------------------------------------------- Op deze e-mail zijn de volgende voorwaarden van toepassing: http://www.fontys.nl/disclaimer The above disclaimer applies to this e-mail message. ----------------------------------------------------------------

If I understand B.Blauuws mail correctly, there already is that possibility:

yes. Just get the above mentiond zipfile and extract the sbm.cbt file.
See below on how to use (example used on FreeDOS bootdisk)
