    Played a bit with the power management today. Couldn't really it get it to do much that'll be useful. I turned on the ACPI in the kernel and turned off APM and rebuilt/rebooted. My power button stopped doing an immediate shutdown and I could cat a file and see everytime I pushed it, which was neat. When I tried to put the computer into S3 it went to sleep, but didn't quite want to wake up. Had problems with both the video and the USB keyboard/mouse. I also had no luck at all finding...

    After much tinkering I finally got advmame to fire up Donkey Kong! It was a problem with the framebuffer driver. Sort of. :-) The site that the driver originally came from used an old style of separating the boot args. It said that you separate args with a : and the values with an =. Well, under the 2.6.11 kernel it's args with a , and values with a : This is what I'm using for a boot arg: video=i810fb:xres:1024,bpp:16,hsync1:30,hsync2:65,vsync1:50,vsync2:100,accel,mtrr Unfortunately it...

    The new computer I'm using has PXE built-in to the motherboard, so I've switched the way I'm booting the computer up slightly. I'm now use the PXE stuff of SYSLINUX. Unfortunately I don't remember how I had the bootsplash stuff setup with the old way. I'm also having problems with bootsplash. I got the latest patches from www.bootsplash.de but so far when I play with the splash util, it complains that it can't find /proc/splash. I'm guessing this has something to...

  • Setting up a Linux box to run MAME

    I wrote about starting to set up a Linux box for the sole purpose of running MAME almost a year ago on alt.games.mame. See this article to see how far I got (or didn't get). Now I'm back on that project again since I'm setting up a fifth MAME cabinet (with a vertical oriented monitor), and quite possibly a sixth (horizontal) soon. All the previous ones have been all Windoze based. Since I messed with this so long ago, I've forgotten half of what I did to get what I barely got...

  • Centipede bench testing

    Finally got around to testing out a Centipede board I got for cheap. Did a bunch of searches and found lots of people making JAMMA adapters but no real details. Decided to just "go for it" and clipped power to the marked test points on the board. For the video I didn't have a smaller edge connector so I followed the pins back to components on the board and clipped onto those. Flipped it on waiting for something to smoke and it came right up! For the video, the yellow clip is...
