Hardware Specification


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.
