Hi Rob,

How are you connecting your graphics card to your screen?

I connect through the VGA port, via a Raritan four port KVM to a VGA screen.

I do not use HDMI.

I have just come home and pressed the space button on the computer and the screen is working. It was not working when I left to go to work this morning.

I wonder if it's due to a screen saver kicking in and making it work (or something). I've just changed the energy saver to one minute, will restart and see what happens.

This is weird.

Rob.

Summary of problem
Gigabyte G31M-ESL MB
Dual Core E6300 CPU's
4GB RAM
Asus Nvidia 9600GT graphics card connected to 17" screen by Raaritan 4 port KVM on VGA port. I don;t have HDMI (sadly)

Black screen on boot after 10.6.2 upgrade. New sleepenabler installed.

Whilst it's bad form to reply to your own mail, I have made a rather interesting discovery.

1. I set the Energy Saver for the screen screen, not PC, to one minute.
2. Rebooted the machine and had the same black screen as I normally get after the update to 10.6.2. i.e. I can move the mouse but cannot see the screen.
3. Left the machine untouched for the requisite minute and the monitor clicked into standby as the Graphics card went to sleep. I know thats not the right phrase but hopefully you know what I mean.
4. Hit any key and lo and behold, my screen appeared instantly. No changes to kexts, uninstalls.

I think the black screen is related to some sort of power saving issue NOT the HDMI copy protection stuff that most people have looked at. Of course my guess is worth exactly what you paid for it, nothing

Hopefully this may help other people.

So, I've been trying for a month to get 5.1 Optical working on this board ( v1) without success using a Gigabyte plug-to-M/B adapter.
I can get light from the hole but no audio comes out.

I've had the sysinfo listing it as SPDIF Combo and SPDIF RCA depending on which kexts I'm trying.

I've got 2 channel output from the 3.5mm stereo no problem but I really want 5.1 for Plex.

Has ANYONE managed to get confirmed 5.1 from this board or do I need to upgrade or switch to another platform.....

Cheers for all the information so far!!

Pete

1st post but a big lurker!! Thanks for the guide especially for a first timer. Fully working and running stable.

Specs are pretty standard:
GA-GM31-ES2L rev.2
E5200
Zotac 9400GT 1gig
Crucial XMS2 PC6400 - 4gig
WD Raptor and Samsung drives
*edit* additional NIC as the onboard ethernet still isn't working

Dual booting on dual drives - OSX 10.6 and Win 7 64bit


One other question...

How safe is using software update in 10.6? There have been some pretty significant updates and I'm just wondering the risk factor when installed from a retail disc.

Sorry everyone another thing just popped up.

Using this guide as a finishing step the Please Sleep kext is loaded onto the system. My question is: Do you have to have the Please Sleep kext and the program loaded in order for the sleep function to work correctly?

Thanks

Steve

Can anybody post the correct BIOS settings for the G31M-ES2L please?

I can't get around the "still waiting for root device" error. I've tried several IDE/SATA settings according to the OSX86 wiki where the problem is mentioned.

My setup is an ide-attached DVD-Rom and an completely unformatted SATA harddrive. As installation method i've chosen the external usb stick. Strangely both devices (hdd,dvd) turn on just before the message of the missing device appears.

thanks for any advice!

I have the same setup - about the only thing I did slightly unusual was to plug in the SATA drive into SATA1 instead of 0. Anyway BIOS-wise I set the SATA to Auto. Everything works fine

GA-G31M-ES2L Rev 2
Encore ENLGA-1320 NIC
Sparkle 9500 GT 512M
E3200 2.4g Celeron Core 2

Hmmm I would think the issue is with the ide drive. I purposely purchased a SATA DVD drive for this build. At $20 it was cheap enough. I have 3 drives in my system; 1 for OSX, 1 for Win 7, and 1 to image the OSX drive so I can make changes without always having to start from scratch.

I think the issue with the drives is that the bios searches for the SATA and IDE drives on the same channel (at least that my take from reading the POST message) and perhaps there are IRQ issues with this in OSX.

Drive config:
SATA 0 - OSX
SATA 1 - Win7
SATA 2 - OSX image backup
SATA 3 - DVD drive

it's safe to update from 10.6.0 to 10.6.2 provided that you remove sleepenabler first before updating and replace it with a newer version of sleepenabler after (get the kext from netkas).

PleaseSleep is a fix for "automatic sleep", even without this app "manual" sleep works just fine. Note that 'the_accidental' from here and insanelymac has a working automatic sleep on his ES2L F10 bios but even after copying his bios settings to the dot or a new install, it's still wont work on me.. weird e.

also a much better alternative is a script called "RIP" from here, both works on my machine but i prefer RIP since it doesn't involve an ugly menubar icon.

i believe i already posted it a few pages back but i'll save you the trouble in looking for it..

here is a PDF came from weeksauce12 from his old 10.5.7 leopard tutorial (Slytherine).: http://dl.dropbox.com/u/3168149/BIOS_Settings_ES2L.pdf
