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...) >I've got Matthias Paul's updated ibmbio.com to boot from d:, but I >haven't tried it with standard OpenDOS.

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). >You can get the alpha version if ibmbio.com from: >http://www.rhrz.uni-bonn.de/~uzs180/opendeng.html Matthias ------------------------------------------------------------ Matthias Paul eMail: Web: http://www.rhrz.uni-bonn.de/~uzs180/mpdokeng.html
