This does not (yet) work, since Windows95 discards OpenDOS & Novell DOS as unsupported OSes for the dual boot. An attempt to overcome this
has been made with my IBMBIO.COM ALPHA1+, but there s more work
to be done to actually enable this feature. (Paradoxically this is because
the DR DOS family has a much improved boot method, whereas MS DOS only loads the first sector of the kernel file...)

Yes, that s it, but IBMBIO.COM ALPHA3+ should allow to get the configuration
files from the actual boot drive, not only C:. However, the actual behaviour
depends on the boot sector, which loads IBMBIO.COM, since the boot
sector code will tell IBMBIO.COM the boot unit.
Improvements are in the queue, but you can also try to patch your
boot sectors. You can get BOOTDUMP.COM (a boot sector register dumper), BOOTLOAD.COM (a LOADER auxilliary to display a menu to boot from any physical drive), and improved versions of GETMBR.BAT, SETMBR.BAT, GETBOOT.BAT and SETBOOT.BAT from me (hope to find the time to put them on my web site soon, older versions of GETBOOT and SETBOOT can be found in IBMBIOA3.ZIP).
