Win7 has DOS-fullscreen error: can't do ?

[NoHtmlMailsPlease]

What is this <DOS Fullscreen mode > about ?

I've got an app which I used to run in dos-mode on my W98 notebook.

Now this Win7 net book gives <can't do DOS fullscreen> errors.

So could I install DOS on a stik, and boot from that [I already put
linux of a CF and boot/use that], and then hope that the hardware can
handle it.

The display hardware is ok for linux., except that I'd like to get a bigger
font
for a certain app that uses the frame-buffer.

Or can Win7 be made to run my app.
I realise now that 'the app' [dosbased ETHoberon] is special, in that it
makes a full GUI on a DOS-OS; obviously by directly controlling the
display hardware, instead of going via DOS.

Please give me your ideas on this matter.

==TIA.
