see that [autoexec] section in dosbox.conf? there you can put all
your mounting, tsr loading etc.

Thanks i have 4dos in the c drive and all of the rest of my programs are in the d drive. Dosbox loads 4dos then i enter the other programs in 4dos. 4 dos is very good to use. It has much more commands than dosbox has.

Yes 4dos is nice, but don't know if it fully works.

I am running 4dos on dosbox 0.70 and everything works perfectly. Perfect speed and everything. Only one thing to know i was fooling around with the commands and found out that typing reboot freezes up dosbox and i eneded up needing to use alt,ctrl,delete.
