[syslinux] isolinux: Extremely broken BIOS detected

Not all implementations (floppy emulation, harddisk emulation, non-emulation mode) are properly implemented/present in each BIOS, so yes indeed, a cdrom with floppy emulation might boot, while another cdrom which uses non-emulation might fail. For example, try the cdrom of Windows2000 or XP. It uses non-emulation mode. Easier: try ReactOS LiveCD (www.reactos.com).

Also the fdos1440.img contains Smart Boot Manager, which contains its own Eltorito stack to replace that of the BIOS. However, it requires that the cdromdevice is on onboard IDE channel.
And it contains Memtest86+ v1.40. The advantages of the SYSLINUX bootloader :)

probably an updated SCSI controller will help. Otherwise, try a $20 IDE/ATAPI cdromdrive.

ISOLINUX requires non-emulation, simple as that. Smart Boot Manager can sometimes help.
