DOS ain't dead

Bug in JEMM (Developers)

Japheth, what do you think about JEMM storing and restoring the size of XBDA (first byte) when returning to realmode and FASTBOOT?
When I load JEMM, my BIOS uses XBDA to read from disk and clears the first byte of it. This only happens when VDS is enabled because with the NOVDS option this is not the case.
