DIY eGPU experiences

[User Retired 2]

My bad. I confused 'disabled' to be the same state as 'empty.'

Strange... I did go ahead and disabled port#2, confirmed with everst.
But when I reboot or shut down and restart, and boot the usb disk, I still get the same general protection fault .
The disabled port#2 also reverts back into enabled state once I reboot it(I checked the 'Apply Save at Startup' box, too).
Do I need to use different save such as Del Sav, Writ Sav, etc?

The bios will revert the ports back to x1 mode. So boot DIY ViDock bootdisk and run DV8000.bat below to turn off port2, and set port1 as a x2 port, then chainload Win7. Likely will do the job for you, assuming the Magmabox driver doesn't alter this part of the configuration.

dv8000.bat

:: Disable pci-e port2 to allow port1 to work as x2 port
:: RCBA+3418h bit 17=1 disables port2
pt MEM write 4 0xFED1F418 0x3A0061

:: Set port1 as x2 port ("x1E" port)
:: RCBA+224h bit 1:0=10 for x2 port1
pt MEM write 4 0xFED1c224 0x81

:: Additional PCI Reallocation/Bridge configuration here

:: Chainload Win7 using bootmgr or MBR method
grub --config-file="menu.w7"
:: grub --config="menu.lst"

Lenovo W510, 4GB RAM (Model 43194BU) running XP 32bit. I really only want to use this external card for 1 or 2 monitors for work use(having 3-4 monitors total - 2 from docking station + 2 from this diy ViDock), I won't be playing any games.. just programming and systems monitoring etc..

My question is, if I purchase the PE4L-EC2C + Power adapter(12v-80w or the gateway 6831 fx 120watt power adapter listed above) what else would I need? what video card would work where I wouldn't need to mess with a ViDock Bootdisk? I have a PCI-e 8400GS, would that work? I read somewhere that NVidia cards cause a conflict with the internal W510 Nvidia card, so what equivalent(and cheap) ATI cards are there? Thanks in advance guys!

If you have a free 256MB window in PCI Configuration space OR can compact the space, then have a good candidate system to do a DIY ViDock. Can't say if you will or won't need to much with the DIY ViDOck bootdisk until you plug a desktop video card in and see how much configuration the bios does for you. A T400 owner reported a PNP setup using a 8400GS here.

I'm having a problem figuring out how to do IGP Reallocation or PCI Reallocation even after reading the step-by-step instructions.

Need Device Manager -> Resources By Connection -> Memory -> PCI Bus sections expanded under C/D/E/F0000000 to have an idea of what's going on.

I have connected external MSI ATI Radeon HD 5770 to my Sony Vaio VGN-FW45GJ laptop.



For system stability, I installed Desktop Cataylst 10.3 and Mobility Cataylst 10.3. My 3DMark2006 (default settings) score is 9829.

I used Antec True Power 430 Watts PS.

... So boot DIY ViDock bootdisk and run DV8000.bat below to turn off port2, and set port1 as a x2 port, then chainload Win7...

dv8000.bat

:: Disable pci-e port2 to allow port1 to work as x2 port
:: RCBA+3418h bit 17=1 disables port2
pt MEM write 4 0xFED1F418 0x3A0061

:: Set port1 as x2 port ("x1E" port)
:: RCBA+224h bit 1:0=10 for x2 port1
pt MEM write 4 0xFED1c224 0x81

:: Additional PCI Reallocation/Bridge configuration here

:: Chainload Win7 using bootmgr or MBR method
grub --config-file="menu.w7"
:: grub --config="menu.lst"

No luck... I created DV8000.bat file using above script, booted the usb, ran the batch file, but it still seems it is getting that general protection fault .
Do I need to edit other .bat files?

do you want x2 config?

or, be in your setting problem of x1?

in the case of x1, you need to set the memory allocation. you MUST allocate your-new-external-graphic-card enough memory, 256mB..

check it surely.

For code12 resource allocation problem, I've solved it using magmabox driver.
So my x1 config already works, but I am trying to get x1E config working.
Would it be possible if magmabox solution is causing this problem ?

first of all, delete magma(useful in x1 but incompatible with x2, this thread)
try it again, with usb boot of ...

Thank you Nando4 for all your help.

Need that screenshot with your 4GB plugged in, rather than 2GB.

Sorry about that. Here they are.

OK - try the following.

:: Setup pci-e port2 using C0000000
@echo off
set port=1
set io_win=8080
set mem_win=cfffc000

:: Relocate Nvidia 48MB from ccxx to f9xx to free up 256MB window at c0000000
echo Relocating Nvidia 48MB window from cc000000 to f9000000...
setpci -s 0:1.0 20.l=fbfff900

echo Configuring underlying bridge hosting desktop video card...
setpci -s 0:1c.%port% 1c.w=%io_win%
setpci -s 0:1c.%port% 24.l=%mem_win%

:: chainload into Win7 using bootmgr/mbr method
grub --config-file="menu.w7"
:: grub --config-file="menu.lst"

Any tests with 8400M and HD5670? I'm wondering about difference, as I'm looking for card for my PE4L.

new results

if anyone wants me to run anything let me know

big hug to everyone


btw the 8400gs scored 1450 or something equally embarrassing...
