Good day Ercolino,
Are you using the ELTORITO.SYS DOS CD-ROM drive driver? You should be,
if you're using MEMDISK.
You might also enjoy some of the discussion here[1].
Also, as an aside, you can create an 8 MB superfloppy image which could
contain your BIOS/firmware upgrade. Maybe search the mailing-list
archive for "superfloppy".
Have a nice day.
