Question about the BIOS and the built-in video card of the laptop?

Question

Video cards

Good evening guys need help. I would appreciate that! BIOS question.
1
Describe the problem.
Not enough video memory. Since the built-in spends from the operative 128MB and the total RAM is 6GB.
I often draw in Photoshop - that's why it is necessary to increase the amount of existing memory of the built-in video.

hd graphics 3000
b) RAM:
6GB
c) Processor:
intel core i3 3220
d)

aser aspire e1-571
3)
What I did (nothing came of it)
I saw videos that can be set in the bios the required volume.
But my bios is not like everyone else's. ((
Here I sit dumb. ((
4)
The BIOS itself looks like (see image)
It basically says how much memory the video card consumes (128mb), but I can’t edit this item.

Answer 1

To sew a normal BIOS (if any) - Acer likes to choose for the user what he can configure - somehow even they could not choose IDE mode / AHCI mode - AHCI was always there, and the old Windows did not digest it due to the lack of drivers.

Answer 2

They immediately offer to sew something :)
To begin with, you can do this (if Windows):

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Intel\GMM]
"DedicatedSegmentSize"=dword:00000256

And reload.

If that doesn't help, try the following options:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Intel\GMM]
"DedicatedSegmentSize"=hex(b):56,02,00,00,00,00,00,00

or

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Intel\DVM]
"DedicatedSegmentSize"=hex(b):56,02,00,00,00,00,00,00

or

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Intel\DVM]
"DedicatedSegmentSize"=dword:00000256

PS This only changes the "messages" from the video adapter to the application how much memory it has. It does not affect how much will be used in the end (HD3000 can take up to ~ 1.7GB).
