zogthegreat Posted April 13, 2019 Share Posted April 13, 2019 Hi everyone! I just tried to do this on my Latitude E7250, with BIOS version A20 and I think that I might have messed up somewhere. I followed the instructions and did the search for my DVMT and I found the following: Spoiler 0x29261 Setting: DVMT Pre-Allocated, Variable: 0x15B {05 91 BC 03 BD 03 7F 27 02 00 5B 01 14 10 01 3F 00} 0x29272 Option: 32M, Value: 0x1 (default) {09 07 BE 03 10 00 01} 0x29279 Option: 64M, Value: 0x2 {09 07 BF 03 00 00 02} 0x29280 Option: 96M, Value: 0x3 {09 07 C0 03 00 00 03} 0x29287 Option: 128M, Value: 0x4 {09 07 C1 03 00 00 04} 0x2928E Option: 160M, Value: 0x5 {09 07 C2 03 00 00 05} 0x29295 Option: 192M, Value: 0x6 {09 07 C3 03 00 00 06} 0x2929C Option: 224M, Value: 0x7 {09 07 C4 03 00 00 07} 0x292A3 Option: 256M, Value: 0x8 {09 07 C5 03 00 00 08} 0x292AA Option: 288M, Value: 0x9 {09 07 C6 03 00 00 09} 0x292B1 Option: 320M, Value: 0xA {09 07 C7 03 00 00 0A} 0x292B8 Option: 352M, Value: 0xB {09 07 C8 03 00 00 0B} 0x292BF Option: 384M, Value: 0xC {09 07 C9 03 00 00 0C} 0x292C6 Option: 416M, Value: 0xD {09 07 CA 03 00 00 0D} 0x292CD Option: 448M, Value: 0xE {09 07 CB 03 00 00 0E} 0x292D4 Option: 480M, Value: 0xF {09 07 CC 03 00 00 0F} 0x292DB Option: 512M, Value: 0x10 {09 07 CD 03 00 00 10} 0x292E2 Option: 1024M, Value: 0x20 {09 07 CE 03 00 00 20} 0x292E9 Option: 2016M, Value: 0x3F {09 07 CF 03 00 00 3F} 0x292F0 End of Options {29 02} 0x29345 Setting: DVMT Pre-Allocated, Variable: 0x15C {05 91 BC 03 BD 03 19 03 02 00 5C 01 10 10 01 10 00} 0x29356 Option: 32M, Value: 0x1 (default) {09 07 BE 03 10 00 01} 0x2935D Option: 64M, Value: 0x2 {09 07 BF 03 00 00 02} 0x29364 Option: 96M, Value: 0x3 {09 07 C0 03 00 00 03} 0x2936B Option: 128M, Value: 0x4 {09 07 C1 03 00 00 04} 0x29372 Option: 160M, Value: 0x5 {09 07 C2 03 00 00 05} 0x29379 Option: 192M, Value: 0x6 {09 07 C3 03 00 00 06} 0x29380 Option: 224M, Value: 0x7 {09 07 C4 03 00 00 07} 0x29387 Option: 256M, Value: 0x8 {09 07 C5 03 00 00 08} 0x2938E Option: 288M, Value: 0x9 {09 07 C6 03 00 00 09} 0x29395 Option: 320M, Value: 0xA {09 07 C7 03 00 00 0A} 0x2939C Option: 352M, Value: 0xB {09 07 C8 03 00 00 0B} 0x293A3 Option: 384M, Value: 0xC {09 07 C9 03 00 00 0C} 0x293AA Option: 416M, Value: 0xD {09 07 CA 03 00 00 0D} 0x293B1 Option: 448M, Value: 0xE {09 07 CB 03 00 00 0E} 0x293B8 Option: 480M, Value: 0xF {09 07 CC 03 00 00 0F} 0x293BF Option: 512M, Value: 0x10 {09 07 CD 03 00 00 10} 0x293C6 End of Options {29 02} 0x293CA Setting: DVMT Total Gfx Mem, Variable: 0x15D {05 91 D0 03 D1 03 1A 03 02 00 5D 01 10 10 01 03 00} 0x293DB Option: 128M, Value: 0x1 {09 07 D2 03 00 00 01} 0x293E2 Option: 256M, Value: 0x2 {09 07 D3 03 00 00 02} 0x293E9 Option: MAX, Value: 0x3 (default) {09 07 D4 03 10 00 03} 0x293F0 End of Options {29 02} I choose the first value of 0x15B and ran the command. This was my output: grub> setup_var 0x15B 0x3 Looking for Setup variable... var name: Setup, var size: 12, var guid: ec87d643-eba4-4bb5 - a1-e5-3f-3e-36-b2-0d-a9 --> GUID does not match expected GUID, taking it nevertheless expected a different size of the Setup variable (got 2638 (0xa4e) bytes). Continue with care... successfully obtained "Setup" variable from VSS (got 2638 (0xa4e) bytes). offset 0x15B is: 0x01 setting offset 0x15b to 0x03 Is everything OK or do I have to dig out my SOC8 clip and programmer? I'm attaching my extracted file. Thanks! zog File_DXE_driver_Setup_SetupPrep IFR.7z Link to comment Share on other sites More sharing options...
