Inspiron 7370: unable to obtain graphics acceleration

[Jake Lo]

If you folder you're adding here is has same name with another, then rename the folder in here, don't override it.

Then copy the new folder over. 

[Bronxteck]

ok I just finally dumped my rom and ran IFR on it my DVMT Pre-Allocated does not have 0x05 it only has

0x00, 0M

0x01, 32M

0x02, 64M

plus the rest we are not interested in since 64M is the highest table it shows

 

I used 0x05 variable which is not on my list  and now I can boot Mojave and HS.

I think I needed minimum of 0x03 or 0x04 for latest HS but it would only load graphics every couple reboots. with 0X05 setup_var mojave boots every time with full acceleration before that it would stop or reboot at graphicslock state 

[tikizondo94]

Well with my extract do you think i would use 0x05 also? Makes me nervous to possibly put in a wrong value lol. 

[Bronxteck]

looks like mine.... I got the 0x05 variable looking at a similar model to mine but one generation older

 

that table looked like this

Setting: DVMT Pre-Allocated, Variable: 0x350 {05 91 62 06 85 06 5A 27 01 00 50 03 14 10 01 FE 00}

Another noob question. Im sorry. How can i determine the "21st" Binary? 

00FFFFFF FFFFFF00 4D10DD21 01010101 00170103 80462778 2A10F5A5 5851A325 125054BF EF809500 81C08140 8180A940 9040B300 81000474 0030F270 5A80B058 8A00BA89 2100001E 00000010 00000000 00000000 00000000 00000000 00FD0014 4D188C1E 000A2020 20202020 000000FC 00504E2D 4B333231 0A202020 20200134 02032BC1 83010000 6E030C00 1000803C 20008001 0203044F 10051F14 20041303 02121106 07151623 09070100 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000036 

[tikizondo94]

So 160MB would be a better option than 192MB?

[Jake Lo]

every two words equals one Byte-count from zero

in your example, it's 

00FFFFFF FFFFFF00 4D10DD21 01010101 00170103 80462778

[Bronxteck]

I did not try 0x06

I guess for 21'st binary start at the beginning and don't count the spaces

 

ok I just tried 0X06 192MB it loaded to desktop froze a second then rebooted. on second reboot it booted fine. my ram dynamic max is the same 1536mb I'm about to take a leap of faith and try

Option: 2048M, Value: 0x40 lets see if we break it

 

Edit.... yup definitely broke it nice yellow flashing power button better me then you 

 

[Jake Lo]

Feeling brave, Bronxteck!

Ok. I modified my EDID data in a random folder from S/L/Displays/etc....Copied the folder to my desktop, Modified the 21st binary to A5 within My DisplayVendorID-4d10 Folder. Renamed the Folder to DisplayVendorID-4d11. And added. Now do i still need to inject EDID within clover? Also remove the custom EDID i originally had in my plist?
