Yes...Windows 98 will do this as well. It does it on my I-Opener, which doesn't even have a floppy header. But try disabling it in the BIOS, some people have good results doing that.

ISTR the reasoning behind this is that some crap OSes (or is it some crap BIOSes?) won't boot floppy images from El Torito bootable CD-ROMs unless the BIOS thinks there's a physical floppy drive present.
