Hi,

I want my installation screen to be at 1024*768*32, so I added these lines in the hivesys.inf file:

Quote

HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.BitsPerPel",0x00010001,32
HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.XResolution",0x00010001,1024
HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.YResolution",0x00010001,768
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.BitsPerPel",0x00010001,32
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.XResolution",0x00010001,1024
HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.YResolution",0x00010001,768

This seems to work well if there aren't any drivers installed. So on a virtual machine, the whole installation runs at 1024*768, but on my pc, the installation starts in 1024*768, but when the drivers are installed the resolution goes back to 800*600*16.

Does anybody know how to fix this ?

Maybe it's good to know I have an nVidia card (driver v84.21 atm)

thanks in advance!

I use this in my winnt.sif file to set my display res.

[Display]
BitsPerPel = 32
Vrefresh = 60
Xresolution = 1280
Yresolution = 1024

Forgot to mention, this is also in my winnt.sif file

but the resolution change for the installation screen (GUI mode) only works with those hivesys.inf settings no ?

I've found a fix:

running this before my XPlode file (that needs a 1024x768 resolution):

Quote

rundll32.exe NvCpl.dll,dtcfg setmode 1 1024 768 32 60

this only works for nVidia cards, and if the driver is installed before you run this command

thanks for this fix to Therapy from the laptopvideo2go forums

Thanks man!
I had the same problem.
Now I still have this prob with my acer (Radeon 9700 card)
But there is no fix for this I think.

also don't forget to edit these lines in your winnt.sif file:

[Display]
	BitsPerPel=32
	Xresolution=1024
	Yresolution=768
	Vrefresh=60
	AutoConfirm=1

Vrefresh=60

This is only the refresh rate of your screen. If you have a laptop, normally the maximum is 60

AutoConfirm=1

This is what I think, automatically confirms these settings, so that you don't have to click on "OK" at first boot, don't know for sure!


If the code in winnt.sif and hivesys.inf aren't working, I shouldn't know what the problem is!


Are you installing video drivers? On my pc, if I do that, the driver sets the resolution to 800x600x16. This can be fixed by running this after driver installation (if you have an nvdia card, don't know for ati what it is):

rundll32.exe NvCpl.dll,dtcfg setmode 1 1024 768 32 60

Sorry, I did read it too fast, didn't see it was only on your acer (ati)

I will search and let you know if I find anything
