Differentiated System Description Table (DSDT) - DSDT is a part of the ACPI specification and it supplies configuration information about a base system. ACPI capable computers come with a preinstalled DSDT from the manufacturer. A common Linux/OS X problem is missing ACPI functionality (fans not running, laptop screens not shutting off, etc.)
This subforum is dedicated to patches/fixes able to be inserted/modified from an extracted dsdt.dsl, which is then compiled into a DSDT.aml for OS X to pick up and use (with a proper bootloader).
These fixes are not permanent, and do not damage your BIOS.

Lan Mac Address In Dsdt
As result LAN is not working without mac address.
No tools available to rewrite missing data.
And once I set any mac address in device properties all is working fine.
It is possible that in DSDT could be added some info to rebuild missing BIOS data?
If yes,how and what to add to DSDT?
ptrB0 =(char *)csrBase + B2_MAC_1;
bcopy (ptrB0, &addrMAC, ETH_ALEN);
bcopy (ptrB0, &MAC, ETH_ALEN);
ERROR_LOG("%s MAC_Address=%02x:%02x:%02x:%02x:%02x:%02x\n", getName(),
