blank screen at boot

[Handjor]

I have a jamma arcade with a wells Gardner 25k7131. installed groovyarcade (june release)onto a usb drive and I am trying to boot to groovy arcade. The monitor is not displaying blue menu and a just get diagonal lines running across the screen. the jamma card lights ddon't light up either.

My video card is an ati hd 4870. I knowthere are monitor settings, but I can't see the screen to make adjustments.

Are there other steps to take to make thus work? I can't find a tutorial or how to document anywhere. If someonecould help me gr8 et going is be glad to contributewhat I learn to a wiki or somethingfor others.


I guess I'm just lost.

Thanks,
Jordan

Hi Handjor,

#1: Have you ever got any proper picture with that monitor + video card + jamma card combo? (I mean, not with GroovyArcade, but Windows + Soft-15Hz, etc.)

I just want to make sure because one should only try these methods once he's got a solid working system and knowledge of which card output is the right one to use, etc.

#2: Did you install the live-cd onto the pendrive using a different computer/monitor and then tried it on the arcade machine?

Although this can be done successfully, it needs some additional amount of tweaking because the video settings originally used for installation are since then used on grub's kernel line, thus preventing a 15-kHz output.

#3: Did you try booting from the live-cd on the target machine/monitor?

If someonecould help me gr8 et going is be glad to contributewhat I learn to a wiki or somethingfor others.

  No problem. It's just that I've heard that a number of times before and still no wiki

I have not gotten the arcade to run on Windows do I need to just forget about it through the name right now in focus on installing on Windows XP?

I installed groovymame to usb with a mac.

how do I adjust settings for groovyarcade before booting? is there a way to modify monitor settings on the USB drive on a different monitor.

thanks again

You'd better use the live-cd to boot on the arcade machine, then install to the pendrive from the arcade machine too.

I'll try it tonight and let you know what happens. Thanks.
