Take a look here for some detailed hacking information : Hardware Hacks for the LS2

Main Board
The following hardware can be found on the main board :


 * IDT 79RC32434-400BC Integrated Communications Processor, containing
 * 32-bit @ 400MHz MIPSel CPU core (el -> le -> little endian) with MIPS32 instructions set architecture. Based on the MIPS 4Kc core.
 * 10/100Mb Ethernet channel {:MII:Media Independent Interface}/{:RMII:Reduced Media Independent Interface} interface controller
 * Serial UART, 16550 compatible
 * DDR memory controller, can handle up to 256MB
 * general purpose memory controller
 * PCI controller
 * DMA controller
 * I2C bus
 * general purpose I/O connectors
 * JTAG interface (hardware-supported debugging)
 * Watchdog timer
 * No FPU (floating point is done via software emulation)
 * |REALTEK 8201CP 'PHYceiver' - Physical Ethernet tranceiver, connected to the ICP's Ethernet channel
 * RAM - 64MB Micron MT 46V32MI6-SBC SDRAM
 * Flash ROM - 4MB Macronix MX29LV320T.
 * IT8211 PCI IDE disk controller. The stock kernel driver reports an IT8212 (an IDE RAID 0/1/0+1 controller). However, there is indeed only a IT8211 on the board.
 * USB - 2 type A connectors (rear - /dev/usb/lp0, front - /dev/usb/lp1) - NEC D720101GJ. The NEC chip supports five USB interfaces, of which only two are connected to the two plugs. Experienced tinkerer can try to add more USB plugs, according to this here.

Software

 * Stock Firmware - 2.x series
 * OpenLink available
 * FreeLink available
