Hi List, Thought I would interject on this one...sorry, I did not quote any of the original message...but, the question was asked if the user could boot into a prior version of DOS on a computer with Win9X installed? YES!!! BUT---the installation of Win9X had to be an "upgrade" of an existing MS DOS system, specifically MS DOS 6.22 and earlier. Then, at the time of upgrading (if that's what you choose to call it, hehe) the user is asked if they wish to keep their current version of MS DOS or replace it...or it will also compress the current system files for previous versions, in case you desire to uninstall Win9X. IF the user chose not to keep the replaced OS system files, they will NOT be available. The only way to boot into a prior version of DOS will be to install that prior version into a completely new and different directory, say something like C:\MSDOS622, and the next step will entail editing MSDOS.SYS on the Win9X files to enable Multiple Booting (BOOTMULTI=1, I think) or do like I did, and use XSetup 2.0 or TWEAKUI to change MSDOS.SYS. Then, you need to enable the Boot Menu to allow booting to previous DOS. To finish, it is possible to boot into any version of DOS on a Win9X machine, provided NONE of the System files were removed during Win9X installation. C U L8R!
