See my E7450 guide for reference. Mainly you need to check the prerequisite to set DVMT preallocated memory to 96MB. Bootpack for E5458 is in post #2 of the installation guide.

I see you have the E7450A10 bios on your desktop. Your system is not E7450.

Use Universal BIOS Backup ToolKit 2.0.exe to extract the BIOS from your system, then save it.

Then use UEFITool to open the file. Search for SETUP....etc.

it's all in the guide.

I opened the Dell.Inc-A10 file using UEFI Extract, generated a folder and a txt file that I do now, I do not know how to generate the file setup.bin

So DellInc.-A10.rom is the version of your BIOS? Make sure it's not for a different system. My guide is use as an example only.

Ok, once you exported the rom file, open the file with UEFITool.exe, not Universal IFR Extractor.

Search for Setup. Once you find that, extract PE32 image section(setup.bin). 

Open the bin with with the Universal IFR Extractor to convert to a txt file

Open the txt file with notepad and search for DVMT.

This will lead you to the location of the value.
