Welcome to EGPU – DSDT OVERRIDE Simplified !

This guide for those who are having trouble with Errors compiling the DSDT to use with EGPU or those who needs a guide on HOW-TO compile the DSDT.

Before we begin please download the following :

  1. Download Free Java
  2. DSDT-Editor – ALL

For this guide we will be using :

HP ProBook 4530s

HP Probook 4530s I3-2350M 8 GB 1600 Mhz 240 GB SSD NON-INTEGRATED
  1. Extract the DSDTEditor_CGC_ALL
  2. Open DSDTParser

Now you can see that DSDT Editor is running !

Go to File tap and click EXTRACT DSDT, and then click on DEVICE_PCI0 on left column see below :


Search for : DWordMemory and scroll down all the way to last DWordMemory section and paste the following QwordMemory :

QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x0000000000000000, // Granularity
0x0000000C20000000, // Range Minimum
0x0000000E0FFFFFFF, // Range Maximum
0x0000000000000000, // Translation Offset
0x00000001F0000000, // Length
,, , AddressRangeMemory, TypeStatic)

So its going to be like this :

DWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x00000000, // Granularity
0xFEE01000, // Range Minimum
0xFFFFFFFF, // Range Maximum
0x00000000, // Translation Offset
0x011FF000, // Length
,, , AddressRangeMemory, TypeStatic)
QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
0x0000000000000000, // Granularity
0x0000000C20000000, // Range Minimum
0x0000000E0FFFFFFF, // Range Maximum
0x0000000000000000, // Translation Offset
0x00000001F0000000, // Length
,, , AddressRangeMemory, TypeStatic)

Once you paste the QWordMemory Search ((IMPORTANT)) for and DELETE the below Line :

If (CondRefOf (FPED))
                    FPED ()

Now click on IASL > Compile & it should go well without any errors at all, once done click Save as and name the file DSDT4530S.DSL.

Close the DSDTEditor and open CMD as ADMIN and go to extracted DSDT FOLDER by using the cd command.

Type in CMD :

asl /loadtable dsdt.aml

Please note that the dsdt.aml might be named as DSDT4530S.aml so please make sure before using the above command, or if the file is not created then use this command :

iasl -oa DSDT4530S.dsl

IF you are on Windows 8 – 10 then please be sure to type this in CMD :

bcdedit -set TESTSIGNING ON

Congratulations ! now you have a working DSDT for your EGPU soultion !

For ATI HD6X 7x you must use DNA Modded drivers link below :

CGC thank you for reading this small guide and we hope this fixes your issues with DSDT-OVERRIDE.


Windows Basic Command List

Some Commands you need to know for basic DOS use

ATTRIB Command Prompt

Command and Usage Examples
Change file attributes. ‘+’ adds an attribute, ‘-‘ removes it. Attributes are: A=archive; R=read only; S=system; H=hidden.
All these attributes will be removed from virus.exe.
Go to the C: drive. Similarly A: and D: etc.
Change directory. When you change directory, the prompt changes, showing the path of the directory you are currently in.Note, directory is the term used by DOS for what Windows calls a folder.
CD\ takes you to the top of the directory tree (typically to C:) .CD.. moves you one level up the directory tree (i.e. up towards the root directory).

CD <DIRECTORYNAME> takes you to that directory. You can use one or more subdirectory names, separated by \ e.g.
CD WINNT\Media takes you to the directory C:\WINNT\Media

To change to another path, type the full path with slashes. e.g.

Clear the screen.
Delete one or more files in the current directory. Can be used with the ‘*’ and the ‘?’ wildcards.DEL *.* will delete ALL files in the current directory, USE WITH CAUTION.(Note: DEL cannot be used to delete directories. Use RD to remove a directory.)
DEL <VIRUS.EXE> deletes virus.exeDEL *.JPG will delete all files with the extension JPG.

DEL MY*.* will delete all files beginning with MY and with any extension.

DEL MY??.* will delete files that are 4 characters long and begin with MY and with any extension.

Displays the contents of a directory (folder).Note, directory is the term used by DOS for what Windows calls a folder.These switches can be combined, so DIR /W /P will return multiple rows listing a page at a time.

You can use the ‘*’ and the ‘?’ wildcards to search for a particular file. The ? character represents ONE character, and the * character represents multiple characters.

DIR *.* lists all the files in a directory.

DIR displays all files and folders in the current directory. Folders are indicated in the list by <DIR>.
Files are usually listed by name.DIR /P displays the contents a page at a time, i.e. as many as will fit in your command line window. Press any key to display the next page.

DIR /W displays the files/folders in multiple rows. This view gives less information per file.

DIR *.JPG displays all files with the extension JPG in the current directory and all subdirectories.

DIR MY??.* displays all files beginning with MY, exactly 4 characters long, and with any extension.

DIR /S lists the contents of all subdirectories.

DIR /AH displays all hidden files.

Runs DOS EDIT (a simple text editor). Useful for editing batch files and viewing logs. This command requires QBASIC.EXE to be present.
EDIT <VIRUSLOG.TXT> opens the file viruslog.txt and allows you to edit it.

EDIT <NEWFILE.TXT> creates a new file called newfile.txt and opens it up for you to edit.

Displays DOS Help. For help on an individual command, type HELP then the command for which you want more information.
HELP DIR displays information on the DIR command.
Make directory. Creates a new directory below the current one. (The command can also be written as MKDIR)
MD <NEWDIR> creates a new directory called Newdir.
Prints the specified file (if the printer is supported in DOS – many are not).


Remove directory. Removes a subdirectory of the current directory. The directory you want to remove must be empty of all files. (The command can also be written as RMDIR)
Rename a file. You must use the full file name including the suffix.
Displays the contents of a file on the screen. If you use this command on a file which is not a text file, the display will be unintelligible. Use with “|MORE” to display the text on a page by page basis, and prevent it scrolling off the screen. “|” is a pipe character.
When you run a DOS command, output is usually sent to the screen. Use > to redirect output from the screen to a file. It runs the command preceding the >, creates a file in the current directory with the name you specify, and sends the information/output returned by the command, to that file.

e.g. SWEEP > REPORT.TXT The details of any infected files reported by SWEEP are sent to a file called REPORT.TXT.
