Hey, dude.
Yeah, most people happily use their 5450s without a proper frame buffer and without any complaints.
A fully functional framebuffer will mostly give you better performance (albeit relatively marginal i suspect) and improved support in a number of apps and games, especially DVD Player which crashes without a proper framebuffer.
The problem you're having with Eulemur, as it is on your machine, is a classic framebuffer personality issue. Basically OS X is sending the wrong kind of signals to the wrong ports on your card, hence the blank display on certain ports. A quick patch to the ATI5000Controller.kext file generally sorts out the signals and get them talking nicely again.
I've attached a patched kext (OS X 10.7.0) version for your card to test.
Included is a text file containing the outputs from your VBIOS Dump and a quick guide to doing the patch yourself, should you ever need to update OS X (which over-writes this patched file) or should you feel like experimenting a little yourself...
Good luck and let me know how it goes.
I greatly appreciate your help with this issue!
I have tried the kext you gave and this is the results:
Card shows as 5450 1024mb in system info
dpcimanager shows Eulemur with 3 ports
DVI working perfectly
HDMI mirrors dvi and doesn't work by itself
vga doesn't work at all
Does the fact that I'm forcing 32bit for my wireless card play a role here?
I'm curious if I didn't mess up the rom dump, as this line is confusing to me:
"CEARD DDR3 128X16 A5103LAA.CGK -H 2011 "
128x16 = 2048 so that cannot be correct for my card right?
I am studying your included txt file, It has helped me understand more about how to fix this kind of issue!
EDIT:
By studying your included text file, I have made the following changes after comparing files with your guide posted
here
I made the following changes to my hex:
Code:
Eulemur Personality: Lion 10.7 Patched (After)
04 00 00 00 14 00 00 00 00 01 00 00 10 00 01 02
00 08 00 00 04 02 00 00 00 71 00 00 21 03 04 04
10 00 00 00 10 00 00 00 00 00 00 00 00 00 00 01
Card shows as 5450 1024mb, using uelemur frame buffer. My dvi and hdmi are working fantastic now, together and separate. when using dvi+vga or hdmi+vga shows in display settings, detects monitor and res but displays nothing on monitor.
I can't thank you enough for helping me understand this much so far!
EDIT again:
changed the vga to have the 10 in the 3rd to last position. everything is working great.
Confirmed card can not do three out at the same time. only dual using any combination. You need a card w/ display port for that.
Code:
Eulemur Personality: Lion 10.7 Patched (After)
04 00 00 00 14 00 00 00 00 01 00 00 10 00 01 02
00 08 00 00 04 02 00 00 00 71 00 00 21 03 04 04
10 00 00 00 10 00 00 00 00 00 00 00 00 10 00 01
