Great. As long as it works for you.you have better performence with 1GB.

Yes. I have the same syptom as yours.I have to hit keyboard several times, and eventually it wakes up...... I turn it off most of the time..

I tried several way to fix the internet problem including yours, so far no success. I just start to do hackingtosh and haven't started to mess with DTST (a lot home work to me).

real quick cause I gotta drive to a job: forget SleepWatcher - the NIC gets deactivated on BIOS level, and not (always) correctly reactivated on wake-up. This needs to be tackled in the DSDT. I ran all compilable patches in DSDT patcher, that didn't solve this. Google for something like "DSDT BCM5722D.kext sleep" or "DSDT wake up lan after sleep" or "DSDT wake up nic after sleep". I am totally sure this has been solved yet, just a matter of looking.

grfx card: oops, I must not have followed your link (256MB version) directly 'cause I ordered the 1GB version .. just $10 more after mail-in rebate .. works good res. + QE/CI - just tested on VGA so far. The only odd thing is that I need to press a keyboard key TWICE for OS X to wake up, the second key about 5 seconds after hitting the first key - otherwise it goes back to sleep, hmmm. Doesn't matter if the ATI5000injector kext is in E/E or S/L/E. Adding Eulemur as ATIConfig string doesn't help, either. That oddness did not change in 10.7.3 (and neither did the NIC-in-BIOS reactivate as expected).

Does your 256MB version wake up right away from sleep with *one* keyboard stroke?

Thanks for your suggestion. I have both similar configure SFF and DFF 745........but I use SFF for hackingtosh

Here is the link for graphic card. It is not a powerful one, but serves my purpose.


I will follow the clues you siad to fix the other two problems.

Hi carrick, thanks for your report. Would you please post the online-shop (or model page) link to the exact ATI 5450 you purchased? I have made the exp. several times in the past that a 1234 w. xyzMB from e.g. MSI would fully work in OS X, and the "same" from PNY etc. not ....

re. Ethernet: search here in the forum for how to correctly unload kexts BEFORE sleep, then REload them on wake-up. Might work, worth a try. Might also be something that can be tweaked in the DSDT, but I don't know details.

re. iCloud etc.: have you tried the iCloud fixes that are floating around? Wasn't there even an iCloud fix offered in iAtkos L2 (even though I don't see it in the screenshot above)?

My 745 SFF is a bit pending right now so I don't have it in my sig yet .. After getting the grfx card I need to see if it even needs a new mobo .. worth it I guess 'cause it's running with a Core 2 Quad.

I installed lion successfully on 745 SFF by using iAtkos L2. Graphic card ATI 5450 works out of box.
But I have the same trouble as others. Network stops working after waking up (BCM5722D.kext, have to restarty computer to gain access to internet),
and also can not log in icloud and some other i-stuffs.

I used iAtkos L2 (Lion 10.7.2) and works great.

Used the same as is in the pic:

Works: Sound, Network and Video card.
GeForce 8600 GT WIth Dual Monitor (NVEnabler64.kext with kext ultillity) and for the Ethernet I'm using a Dinex DX-PCIGB PCI and the nic board (BCM5754)
