I've added Transpercy and a custom background to the classic setup. And it all worked fine on the default resolution. All i've changed was: HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.BitsPerPel",0x00010001,24 HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.BitsPerPel",0x00010001,24 Since it was a 24bit 800x600 bmp image. But when i changed the resoution of the setup to 1280x1024 everything stopped working. The background was black and no transpercy HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.BitsPerPel",0x00010001,32 HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.XResolution",0x00010001,1280 HKLM,"SYSTEM\CurrentControlSet\Services\VgaSave\Device0","DefaultSettings.YResolution",0x00010001,1024 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",0x00010001,1280 HKLM,"SYSTEM\CurrentControlSet\Control\Video\{23A77BF7-ED96-40EC-AF06-9B1F4867732A}\0000","DefaultSettings.YResolution",0x00010001,1024 You can see i used 32bit in the settings but that doesn't matter i guess since i tryed with 24bit with the same results. Could it be that SETUP_W.BM_ is too big?. The size is 1.5MB Too high resolution? I used 1280x1024. Everything worked fine on 800x600 so why doesn't it now? (And no I didn't set it to use black backround in Nlite ) Some help would really be apreciated. Btw. I only tested it on VMWare and Virtual PC.
