The Malta board has an Intel 82371AB PIIX4 (aka Southbridge) which provides the following:
- (2) PCI IDE controllers (One controller is dedicated to the CompactFLASH socket.)
- USB 1.1 Host Bridge
- Two i8259 IAC controllers
- One i8254 timer
- One MC146818 style RTC and CMOS controller
On the PIIX4 PCI bus there are the following devices:
- Super I/O chip which provides:
- 16550 compatible DUART
- LPT port
- Floppy controller
- PS/2 keyboard and mouse
- Cirrus Logic CS4281 AC'97 audio codec with AMR riser
- Am79c970 PCnet-PCI Ethernet controller
Malta board may be equipped with various "core cards". A core card includes a CPU, a system controller (aka Northbridge) and SDRAM module.

Malta uses YAMON for its firmware. YAMON determines various Core card models and their endianness automatically. The YAMON image contains Big and Little endian parts and "magic" code to determine the current endian.
There is RedBoot port to Malta too.
The Malta is fully supported by Linux 2.6 and current Linux 3.x kernels. The main Git tree hosted on linux-mips.org is geared towards bleeding-edge development. There is a separate tree that is geared towards absolute stability on Malta as well as the SEAD-3 platform. It is actively maintained by MIPS Technologies, Inc.
Malta board is the most popular platform for MIPS full-system emulation.
GXemul supports MIPS Malta CoreLV (CoreID=1) well enough to run unmodified Linux 2.4 and 2.6 kernels (except PCI and LAN stuff).
QEMU also support MIPS Malta architecture.
- OVPWorld MIPS Homepage OVPsim simulates the MIPS Malta platform.
- Virtutech Simics Developer also emulates Malta.
