Just reevtnly I tried to upgrade my DOS
version from 5 to 6.22 using the MS supplied
STEUP package. Well what a !@#$%^& MS made
of that. 

I wont go into details of all the stuff
ups but the main one is that when I do the
upgrade it wipes over the boot manager
i.e. F1: DOS, F2 FreeBSD etc

What is the reccomended way to get the boot
manager back after I install the DOS upgrade.
I presume that there is a program (mbr ??)
which writes the boot manager code to the
sector 0 on the disk.

Alternatively I can write a program to do this
i.e read sector 0, save to file and rewrite
it after the 6.22 upgrade. Question is 
doe the boot manager only use the
first 512 bytes ?? or more !!

Thanks

Jon
