No, you can't just replace the system files in general. The boot sector will likely need changing. I don't know how DM does what it does. DOS versions prior to 4.00 are unable to handle partitions of over 32 Mb (with the exception of some special flavours, e.g. Compaq DOS 3.31). The only way I know of to reliably and safely upgrade your DOS version is to back up, reformat, sys, and restore the boot drive. You must be careful doing this, however; when you back up, make sure you boot with the NEW DOS version, since the BACKUP/RESTORE programs for various versions of DOS use different file formats! I have my hard drive partitioned so that the C: drive is only about 1M; it includes DOS, Disk Manager and drivers for the config.sys file. Should I decide to upgrade my DOS version (but continue using Disk Manager), all I need to do is to reformat the one partition, rather than, say, a 30 Mb partition with DOS, Symphony, Turbo C, etc... -- Stephen M.
