It works
I use dos on a old pc of mine  
If you are looking for a full ring dos mode, not the striped down win9x dos mode    
try dos 7.1
http://ms-dos7.hit.bg/
It is free and quiet nice and has a lot off cool software with it

thanks for ur help it will try that see if i can get it to work. what is the best way to install dos 7.1 b4 win98 or after win98 is installed? what are the best drivers to use for voodoo 2 i install 3dfx driver 3.02.02 are the FastVoodoo2 drivers better. i ant use voodoo 2 since back in the day lol i miss playing all the old games. i dont know anything about these new drivers so some info could help thank for ur help

burn dos 7.1 to disk
boot up the pc
put the disk in your cd-rom drive
you may need to set your cd-rom drive as the boot first boot device in  your BISO  
install dos 7.1 it will detect win98 and let you a choose a boot option
for it
