VIA EPIA M Motherboard

The CG-8 uses a VIA EPIA M mini ITX PC motherboard produced in the early to mid-2000s. It uses the VIA CLE266 chipset and comes with 512MB RAM in its single UDIMM memory slot and a 2.5in 40Gb hard drive, connected via IDE. The Retro Web provides comprehensive information about the board and notes that - like many computers of its era - it is prone to "faulty or leaking electrolytic capacitors".

Notes:

512Mb RAM

The RAM is in the form of a single 512Mb DDR UDIMM PC2100. According to the user manual, the motherboard has a maximum RAM size of 1GB.

40Gb Hard Drive

Notes: The 2.5" IDE connector is not well-suited to regularly plugging and unplugging while testing, It's easy to bend and misalign pins. SATA is much more robust. I therefore use an IDE to SATA cable and use Hitachi 40Gb SATA HD drives. I have tried an SSD drive, but so far without luck. To copy your existing hard drive to a new disk see the instructions below.

Diagnostics

Before doing any work on the CG-8 you should back up and clone the internal hard drive. It is strongly recommended that you don't do any diagnostic work with your original hard drive in place. Also, be electrically safe.. Some areas of the CG-8 internals carry high voltage, even when the power is off. particularly the power boards. Do not be tempted to plug/unplug anything while the power to the CG-8 is on. Doing so is likely to cause damage.
