eox3 compatibility test

[mpp.eox3]

eox ran fine on a real computer a few years ago.
but with the time I only started to test my kernel in vmware/bochs and I somehow restarted the whole project about 2.5 times, so the revision 3 kernel was only tested in vmware & bochs (quadsmp)

so.. I don't know if eox3 runs smoothly on a real PC, could somebody please check this out?

I think I should go and get a bootable USB stick - my dev laptop has NO FLOPPY DRIVE.....

If you see a message "system halted", everything is fine.

THANKS for your time

No, sorry, doesn't boot at all, hoped to see a GUI, or something.. but it didn't happen..
Maybe you could use these information pieces:

hmm...

the >>PANIC<< POWER button turned off thing is normal.
the last thing that was done then is some videostuff.

i get the same grub messages, so the kernel should be loaded properly.

I think your bochs doesn't like my strange videomode. I think I'll disable that and make two test releases.

Which bochs version do you have?
Mine is ver 2.0.2, january 21 2003, compiled with 4 cpus.

thanks


NOTE: there is no gui yet. just a textmode startup screen.
after initialization is done, the kernel halts.

ok, downloaded the newest bochs 2.11, now I know what you're speaking about..

I can't see anything.

I just skipped the videomode initialization and everything works fine without an error
Maybe the kernel worked fine before but you couldn't see anything because the colorpalette was all black (black text on black background looks just too good..). I'll play around a little bit...

So did I, and I know >>PANIC<< power off means that I pushed the power off button (virtually )

Where can WE download YOUR new version ?

[mpp.eox3]

still hacking the vga registers...

this will take a while.. But I know now where exactly the problem is. I just have to make it bochs compatible..

[mpp.eox3]

k got the vga to do what I want. Build 2258 works now in bochs 2.11 too:
