ok..here is my problem in doing the PCI reallocations..the 4th step..how to do it for windows 7/32??i try to type the code in the command prompt..but the bcdedit cant be open..said some error..thus i dont understand n stuck here..can anyone explain to me..how to Create a Win7/32 bootloader menuitem using the disk image..
please help me as detail as u can..because i am totally stuck..


i think the next step..i do know how to do it..i already stucked...please reply asap..pleaseeeeee!

ok..now i succeeded do the 4th step..but there was always a problem..because when i try boot the setup 1.x at boot menu..at boot menu..unfortunately..i cannot move my selection..i hope someone can help me..huhuhu..because i dunno why on earth my arrow wont do what it suppose to do..

Hi all. Just found today that you can "do it your self" vidock. So here is my super question. I have a MacBook Pro. Here are the specs MacBook Pro "Core 2 Duo" 2.4 15" (08) Specs (Early 2008, MB133LL/A, MacBookPro4,1, A1260, 2198) @ EveryMac.com . As it has a ExpressCard/34 slot. Can i do DIY ViDock booted to Windows 7 32bit ???

Since you have the express card slot then there should be no problem doing it with windows 7.

I have a MacBook Pro. Here are the specs MacBook Pro "Core 2 Duo" 2.4 15" (08) Specs (Early 2008, MB133LL/A, MacBookPro4,1, A1260, 2198) @ EveryMac.com . As it has a ExpressCard/34 slot. Can i do DIY ViDock booted to Windows 7 32bit ???

This is the second Macbook post we've had. I'll reply to the early one posted:

I'm a MacBook Pro user and I've taken the plunge to see if I can get a the PE4H working with my laptop.

I'm using an NVIDIA 9800GTX+, 480W power supply, and PE4H 1.0 with EC2C express card.
..
Any suggestions or thoughts on why the system would pass POST? Would trying a different video card help? The baseline mac video card is a GT120 which I could pick up to test.

POST presumably is like bios on a PC and it does various device allocation. If it hangs then the Mac "bios" doesn't know what to do with the 9800GTX+. So then, can't have it powered on during bootup.

Then there are two additional issues.

1. PCI Allocation for the 9800GTX. Can Win7 allocate it to 32-bit space on Macbook? If not it would appear with an error 12: cannot allocate resources against it in Device Manager. To correct the error would require some way of applying a pre-OS boot PCI Configuration. eg: DIY ViDock Setup 1.x or using grub2's setpci/write_xxxx commands.

2. Configuring the NVidia card if hotplugging. This is a quirk I found with my GTX470 testing. If the card is hotplugged in DOS while running Setup 1.x, it's detected OK, I can do PCI allocation for it OK but it will hang Win7 loading. The workaround solution I found being:

(i) apply the PCI allocation (if needed), but poweroff the NVidia card. Chainload into Win7, standby, poweron NVidia card, resume. It will be detected and function OK.

(ii) OR load a "good" 8kb PCI configuration into the NVidia card in DOS prior to chainloading. Obtaining that good configuration is done by using hwdirect to save the PCI Config space of the card after doing 1 in Win7 OR saving it in DOS using pt if can boot past the bios with the NVidia card turned on. This method would require that DIY ViDock Setup 1.x works OK.

I'm hopeful NVidia can advise on how to 'configure' the NVidia card when hotplugged.

ok after select from the boot menu setup DIY Vidock..what should i do..it direct me to grub:>....what should i type in that to do the realocation of my memory??please..
nando..or who ever..please help me...
or did i do sumthing wrong..?

[Utamaru]

hershbergien Any luck making it work? Did u try installing the nvidia 9800GTX+ drivers in osx prior turning on the card? And did you try it bootcamped in windows 7? This can help with osx drivers http://aquamac.proboards.com/index.c...lay&thread=528 . But i need to know how it is when bootcamped to win7.

[hannajwa]

how do i know whether i have already PCI reallocated
or not??

[hannajwa]

when i try to chainload..why at the last its stated that

start cmain().....

what is that..and i wait almost 15 minutes..and it seems unresponsive..

can someone tell me..

Sorry for the silence, I just flew home yesterday for some hard earned holidays. No worries, I brought the GTX 460+PSU over so that I keep tinkering with it. This also means I won't be able to collect any HD5750 data until I return (early August).

Excellent post yet again. Only major discrepancy in your x1E versus x1 is Dirt2 DX9 getting 72.86 and 58.99 respectively. Can you double-check that is the result? The other results show x1E and x1 to give exactly the same results when factoring in slight variations between runs. If Dirt2 does show this difference then it's still an issue with Intel chipsets underdelivering only 70-80% of x1 1.0 bandwidth requiring Intel investigation. If Dirt2 shows the same result then it's a handshaking issue with ATI/Older NVidia cards and Intel I/O chipsets that requires ATI/NVidia and Intel investigation.

Yeah I'm also suspicious of that result. The DiRT 2 bench runs are not entirely reproducible because the 8 cars are A.I. controlled and vary in how well they drive between runs. It might have been a weird run (e.g. cars piled up during the lap). I'll run some more runs in triplicate to see if I can reproduce that particular result.

i am sorry to bother everyone..but i am a newbie..and very interested in this DIY Vidock..

my spec is..

XPS m1530...win7/32...T9300 2.5GHz..4GB RAM..nVidia 8600mGT..
try to use XFX ATI HD5770...with PE4L+EC2C connected with ATX PSU 350W..

i am very2 sorry..if all my questions are nonsense..
i want to tell that i already succeeded (i think) in doing the PCI realocation..
using the 36bit...and has reallocated 256mb PCI windows..as stated..

and now..i am confusing how to used the ViDock..as i connected the GPU to my laptop..my laptop recognised it well in the device manager..this is before any driver installation..
but after i installed the 10.6 ATI driver..the 10.6 software can't detect my HD5770..i don't understand this is prior to what??...i tried a lot using a lot of times..and i still can't figure it out..
i also used the 9.8 ATI driver software..but it also fail to detect the HD5770..but my laptop detected it in the device manager..

what should i do nando?? i am currently blur...and helpless..
