Title: Changing the Display Mode
Post by: XDelusion on April 05, 2010, 11:01:38 AM
Once I have AROS installed on a real computer, how do I alter the boot up so that it does not present all the screen mode options and just defaults to the one I choose.

Also how do I get it into 16 bit mode instead of 24? I read in the DOSbox documents that this is necessary to prevent system slow downs.

Thankx!

I have it running in VirtualPox and I`d really love to get it to boot into a resulution that I can actually see without scrolling. Unfortunately the screen mode preferences seems completely broken.

If you really want to fix this on the bootmanager level you should be able to find some info through google: "GRUB" is also used on many Linux distributions and should be documented pretty well. The muliboot options are visible when you press e in GRUB, so you should be able to roll your own, but I havenĀ“t tried any of this.

I had to select GeForce 7800, which is strange because I have an on-board 6100, but it will not work with the top NVIDIA option so 7800 is the only way I could get it to work.

I was surprised to see that I can now change video modes, though 16bit mode did not seem to help DOSbox from making the computer drag at all, though I only have 512Mb of RAM, maybe that has something to do with it?!

BOH's did not like it at all, I forget what I did, but it took forever to get it to display full screen again with proper colors and displaying corner to corner rather than only taking up half the screen.

I'm thinking AROS has some priorities that got over looked.

just edit the sys:boot/grub.cfg file and change default setting at top. note that the first is zero.

when ruuning vesa the screenmode prefs only show one resolution. if you have a native supported nvidia card then you get lots of choices.
