If Clover was installed on a FAT32 partition, then it will be able to save all ORM ACPI tables, including DSDT and FADT. If you were able to start Clover somehow, you can enter its GUI and press F4. Where can you obtain the initial DSDT that needs to be patched? There are different ways involving Windows, Linux or OS X. Alternatively the OS can have its own DSDT in the root of the system partition. When you reached this step you can instruct Clover to use your modified DSDT by placing it into the directory EFI/CLOVER/OEM/xxx/ACPI/patched or - when the computer's name is not known yet - into EFI/CLOVER/ACPI/patched. Non-conformance to the specification, however, should be considered as a warning, not as an error). From my point of view the compiler is not bug-free. (It is a bit strange, compiling/decompiling is not a strictly reversible operation and will change the table or even prevent further compiler operations.

Additionally, you can fix other mistakes, which prevent the PC from sleeping or waking up, or add new devices. 4 : The last part is made impossible because of syntax and logical errors initially present in the OEM DSDT. A user will use this path to apply corrections: AML>DSL>edit>DSL>AML - this is the next point.
#MAC CLOVER BOOT LOADER SLOW CODE#
It can be de-/compiled using IASL, which translates binary code into human readable DSL source code. The DSDT is is written into the BIOS and is used by the system in AML binary code. Additionally it is often necessary to add or remove framebuffers/ports to devices like video cards or SATA controllers.
#MAC CLOVER BOOT LOADER SLOW DRIVERS#
Their drivers do not exist and are not even needed. They should be written into the DSDT however! Vice versa, devices like the internal speaker, floppy drive or parallel port should be excluded. 3 : The vendor of a motherboard's and thus the creator of a DSDT, cannot predict the devices you will be using (CPU, video card, etc.). Many BIOS variants can use the variable OSYS = 0x07D2, but not 0x07D6, 0x07D9 or 0x2410 as written into a real Mac's DSDT. Even if you find Darwin in your DSDT, mask it as Windows2001. It is always correct to mask the system as Windows 2001.
#MAC CLOVER BOOT LOADER SLOW MAC OS X#
Mac OS X makes great use of the ACPI system and uses a DSDT to its maximum, as does Windows 2001 but not Linux, Windows 98 and not Windows 2006. Even if it is not, it was created for FreeBSD. Mac OS X uses identifier Darwin, which usually is missing. 2 : A DSDT contains certain dependencies on the operating system like Windows 98, Windows 2001, Windows 2006 or Linux. Usually a DSDT will still need to be corrected. Does Mac OS X really need HPET? Not really, but BIOS vendors tend to be slow and they just started writing the correct parameters. This kext can either be removed or blocker, however you can alternatively correct the DSDT to ensure a normal behaviour of this kext. The point is that OS X includes a kext named AppleIntelCPUPowerManagement for power management control (SpeedStep), which - by all means - needs interrupts IRQ 0 and 8. Why does it need to be fixed at all? DSDT patching was created with the intention to fix device HPET - High Precision Events Timer. It is better to do the corrections manually. Clover offers an option to automatically apply corrections, however it is important to understand that an artificial intelligence was not created yet and that the automatic method is far from being complete. Correcting this table means you need to have some sort of programming knowledge. These methods can contain arithmetic and logical expressions, representing a program written in a C-like programming language.

This table describes devices and methods for accessing them. The minimal length is 36 bytes, in reality it is about 20 kb or even more. DSDT - Differentiated System Description Table - is the biggest and most complex ACPI table.
