JMicron JMB363 Add-on Card AHCI mode

By Henry, on August 26th, 2012%

The JMicron JMB363 is a 2-port SATA + 1-port PATA controller chip often found embedded in motherboards and in low-cost add-on cards. The chip supports operating in IDE, AHCI, and RAID controller modes. Motherboard BIOSes allow choosing the operating mode, but add-on cards are stuck in RAID mode.

Gigabyte’s new UEFI BIOS is particularly well-suited for building Hackintoshes. However, many of Gigabyte’s recent motherboards, including all of the MicroATX Z77 and H77 boards, use the VIA VT2021 HD Audio codec chip, which is not well-supported. Since I’m building a Hackintosh with a GA-Z77M-D3H with VIA VT2021 chip, I decided to work around the audio issues by swapping the VT2021 with a Realtek ALC885 chip. . . . → Read More: Replacing VIA HD Audio Codec Chip

Gigabyte GA-Z77M-D3H Motherboard

By Henry, on July 3rd, 2012%

Gigabyte makes several similar MicroATX motherboards with the Intel Z77 chipset:

GA-Z77M-D3H
GA-Z77M-D3H-MVP
GA-Z77MX-D3H

The first two do not have manual adjustment of VCore. This is a failed attempt at trying to use the GA-Z77MX-D3H firmware to enable them. . . . → Read More: Gigabyte GA-Z77M-D3H Motherboard
