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.
