I thought it was because fluxbox didn't support scroll wheels.

Okay, quick question which I couldn't find anywhere... is there a way to force 1024x768 resolution - mainly for fullscreen display.

For those with lcd displays - fullscreen bad

Okay, from messing around with qemu for the last couple of days (freedos, Ms dos 7.1, dsl):
I can finally get dsl fullscreen so I can see the bottom bar. Ummm, if your monitor can't handle resolutions below 1024x768 (or maybe below 800x640... 640x480 is the default dos and dsl "text" modes) don't try to run with -full-screen on the command line. Qemu messes up, crashes, things in windows go strange, the mouse freezes... and when I reboot the monitor just displays "This monitor can't handle this resolution - change the input to 1024x768" ummm, which is very difficult to do when you can't SEE! Rebooting into safe mode (press ctrl while booting) deleting the video driver (with no mouse because safe mode doesn't use my usb mouse... and you can't change the resolution because it is set for 16colors 640x480) rebooting, finding the driver, rebooting... finally working again.

Ummm, so yeah I've done this about 20 times this weekend!!!

It seems slower to me... I'll have to experiment more with the old one - maybe because my system is not that much more powerful than the emulated one... so it is not able to run in what is left of the system after winME is running. I don't know - I'll try changing the memory a bit as well. Maybe 192 will be better.

Anyway, just thought I'd give everyone a bit of a warning - fullscreen can mess things up, so try only switching to it when fluxbox is up and switch back BEFORE shutting down....

Sigh.
(Umm, quick question...?

When I need to go fullscreen, I just hit

CTRL-ALT-F

and again to switch back before shutting down QEMU.

Yup, I forgot to mention that - just for some reason you have to switch it back before shut down. No idea why I can boot dsl fine (no monitor troubles) and can get into windows safemode 640x480, but it has trouble after crashing from fullscreen.

Okay, some more testing - copied the original back, and it is faster on my comp - 1ghz Epia. I am not sure how much is because of the increased video - 1280x1024x24 instead of the 1024x768x16 that the original runs on - I tried switching it back, but it doesn't seem to have done much. Also I think a lot is just that there isn't enough room for it to run the P2 on top of winME.

Either version, all memory tries and video resolutions I tried... I still get to 40% cpu usage from moving my mouse around

Anyway, I've got a headache now. I mainly use embedded to look into things while on the board - research for when I boot fully into dsl, so the slower speed does not affect me much - as long as it doesn't crash windows

A higher display resolutionw will definately slow down the performance.

That is why DSL defaults to fb800x600 resolution.

It is the least stressful resolution that is still usable (640 x 480 is difficult to use).

FYI, the QEMU folks recommend that both host OS (in this case Windows ME) and guest OS (in this case DSL embedded) should both be run at 16 bit color depth for best performance.

Hope this helps.
