Snow Leopard working but no video signal

[bossent20]

hi

 

i am very close with snow leopards install

 

i know i am in the initial setup screen for snow leopard because the eject button on my keyboard acts with the dvd tray

 

however i am unable to see anything because the monitor goes into no signal mode

 

my graphics card is a zotac gtx 275. i was able to run this card perfectly well inside leopard 10.5 using the iatkos v7 dvd

 

the install disc for iatkos v7 has a natit enabler for nvidia cards as well as a gtx 200 driver

 

but is it possible to add this to my snow leopard install or can i do it some other way please.

 

if so how?

 

please i am so close. really need some help here

 

many thanks

bossent20,

 

If you're using Chameleon 2.0 RC3-r658 + Netkas' PC EFI v10.5, it should work...

 

Add the following keys to /Extra/com.apple.Boot.plist

<key>GraphicsEnabler</key>
<string>yes</key>
<key>Graphics Mode</key>
<string>1920x1200x32</string>

Be sure to change the Graphics Mode string to the resolution of your monitor.

 

If, it does not work the first time around, boot into single user mode (-v +x) and add this to /Extra/com.apple.Boot.plist

<key>Kernel Flags</key>
<string>-pci1</string>

Save the changes and reboot...

 

This is an override for the default location of the primary graphics card slot (pci-e slot).

 

If you'd rather determine which slot your pci-e is, run this command in Terminal:

ioreg -l | grep -15 "AppleACPIPCI\ " | grep UID

 

Netkas' PC EFI v10.5 seems to rely on dsdt.aml for pci root detection, so make sure you have dsdt.aml in /Extra/.

 

You can find more information on PC EFI v10.5 and GraphicsEnabler at Netkas' website @ netkas.org.

 

Hope this helps!

 

Peace,

 

IanT
