The Fuloong Miniature Computer is equipped with a Loongson microprocessor (manufactured by STMicroelectronics and developed by the Chinese Institute of Computing Technologies), manufactured by Lemote Technologies.
The 2EA2RA model has a Loongson 2E at 660MHz, 256M DDR333 SDRAM and a 40GB Hitachi harddisk.

The CPU on it is a Loongson 2E, which is 95% compatible with MIPS64. It works at frequency 660MHz, and up to 800MHz, with FSB at 66MHz.
It comes with a Hynix 256M DDR SDRAM on the DDR SDRAM SODIMM slot. With 32bit mode, the maximum of SDRAM will be 256M. More memory requires a 64bit Operating System.
The display controller is an ATI Radeon 7000 with 16M display buffer onboard, attached to PCI bus internally. It exports a VGA port and a S-Video port.
A mini-IDE port is on the back side of the motherboard, supports UDMA100 mode and LBA48, provided by VIA VT82C686B sourth bridge.
A Hitachi 40GB harddisk is attached on it.
A RS-232 Serial Port provided by south bridge.
An infrared sensor provided by south bridge.
A 10/100Mbps ethernet port based RTL8139D controller.
- PMON 2000 (Revision 2.x modified by Lemote for loongson)
- Debian 4.0 ("etch"), 5.0 ("lenny"), 6.0 ("squeeze") and 7 ("wheezy"). Version 7 is the final release to support Fuloong 2E as it is the last one compiled for MIPS II ISA support. Later versions require a higher ISA version that Fuloong 2E does not support.
Note: The JIT compiler embedded in Iceweasel 38.8.0esr included with Debian 7 incorrectly produces MIPS code for an ISA version higher than Fuloong 2E supports and consequently the program crashes right away on startup. As a workaround insert:
manually into prefs.js.
