[READ FIRST] Access Advanced settings through EFI shell

[Ian58]

Hi,

I can't use the perl script, it's giving me the same error as other people on this thread...
Do somebody has the result of the perl script for InsydeH20 F.25 rev3.5 UEFI?
I managed to switch to AHCI mode by looking in F.24 logs posted on this thread, by chance the vars 0x36 and 0x39 was used for the same options...

So if somebody could post the entire log for insydeH20 F.25 it would be really great!!

Thanks

Hello,

i hope you can help me

i need some options from my BIOS

Acer Aspire V7-582PG
-Bios Revision : 3.7
-Bios Version: 2.24
-Bios Type : Insyde EFI
- Link to Bios Download: LINK
- Link to current .bin: https://www.dropbox.com/s/bnbfdz0507etq05/ZRQ_new.bin

I need the following:
- Disable Integrated Intel Graphics || Disable optimus || set PEG first in order
- set more Memory for Intel Graphics (looks like the default is 64MB)

I need this in order to install OSx Mavericks on this Notebook.
If possible, can you provide a complete structure dump?

with best regards
Bernhard

- set more Memory for Intel Graphics (looks like the default is 64MB)

Not possible to disable Intel graphics, cause your laptop does not have separate bus to operate with discrete graphics. Intel always "show picture" while discrete is ised for mathematics. But it is possible to disable discrete card.

Disable discrete card
setup_var 0x1e7 0x0

set PEG first (this can cause black screen, MB battery removal can help)
setup_var 0x186 0x1

set more memory
setup_var 0x18c XX

where XX is HEX value

Code:

Option: '0 MB' [ Value: '0' Default: 'false' Type: 'int8' ]
Option: '32 MB' [ Value: '1' Default: 'false' Type: 'int8' ]
Option: '64 MB' [ Value: '2' Default: 'true' Type: 'int8' ]
Option: '96 MB' [ Value: '3' Default: 'false' Type: 'int8' ]
Option: '128 MB' [ Value: '4' Default: 'false' Type: 'int8' ]
Option: '160 MB' [ Value: '5' Default: 'false' Type: 'int8' ]
Option: '192 MB' [ Value: '6' Default: 'false' Type: 'int8' ]
Option: '224 MB' [ Value: '7' Default: 'false' Type: 'int8' ]
Option: '256 MB' [ Value: '8' Default: 'false' Type: 'int8' ]
Option: '288 MB' [ Value: '9' Default: 'false' Type: 'int8' ]
Option: '320 MB' [ Value: '10' Default: 'false' Type: 'int8' ]
Option: '352 MB' [ Value: '11' Default: 'false' Type: 'int8' ]
Option: '384 MB' [ Value: '12' Default: 'false' Type: 'int8' ]
Option: '416 MB' [ Value: '13' Default: 'false' Type: 'int8' ]
Option: '448 MB' [ Value: '14' Default: 'false' Type: 'int8' ]
Option: '480 MB' [ Value: '15' Default: 'false' Type: 'int8' ]
Option: '512 MB' [ Value: '16' Default: 'false' Type: 'int8' ]
Option: '1024 MB' [ Value: '17' Default: 'false' Type: 'int8' ]

for example if you want to set 512 then use value 16 (0x10 in HEX)
setup_var 0x18c 0x10

Please do not try my solution for others if you do not want to brick your laptop. Bios varstores not always the same and applies only to specific BIOS.

Thank you very much,

Ive just tried to set does values but my uefi shell says that setup_vars is not a valid command (using your linked BOOTX64.efi doesnt work, tried a view different shells (Grub, Clover, another efi file i downloaded). EFI Revision: 2.31

sorry i mean setup_var ... mistyped it here

When using your efi file, i get nothing (only the acer logo). When using other shells, i get the uefi shell (yellow text, listing of devices in the beginning etc). help -b doesn´t list the "setup_var" with dmpstore i could print the nvram (but not modify)

[Falseclock]

try this one, it should work. and do not forget to disable secure boot

thank you, that efi shell works for me

thank you, that efi shell works for me

and? how is the process?

[BJockeyR]

I`am testing ... and reading the log file which you have sent me.

Until now MacOSx does not regocnize the changes in the way i hoped , Intel Graphics is always in the first place (and since the 4400HD is not official supported by Mavericks, it only works with 64MB regardless of BIOS Settings)
