Hi Jerome,
just wondering, does your ISO use the newest UDVD2 driver from http://mercurycoding.com/downloads.html#DOS ? Note that the readme in those downloads might need some double- checking, but as far as I remember, the binaries are fresh. Note that when you BOOT FROM VIRTUAL FLOPPY, you do NOT need UDVD2! Instead, you can and probably should provide the option to use the ELTORITO.SYS driver which uses BIOS assisted CD/DVD access :-) That only works for the CD/DVD from which you have just booted, so the system installed on C: afterwards cannot use the El Torito driver.
