Known issues:

• Leaky Ni-Cd clock battery

The Ni-Cd battery may be leaking, risking damage to PCB layers & nearby components. Promptly remove the battery & clean corrosion/alkaline salts from the board. Use white vinegar to dissolve salts, but exercise caution as vinegar can corrode exposed metals. A thorough examination & repair may be needed.

• Fake cache

The motherboard may include a non-functional or counterfeit SRAM cache, which can adversely affect performance. Signs of fake cache often include soldered QFP or DIP-chips labeled "WRITE-BACK" with traces that do not connect to the chipset.

• DIP chips can typically be removed and replaced with functional SRAM chips in sockets to restore cache functionality.
• QFP fake cache chips are often not replaceable with functional cache as the PCB footprints are not chipset connected.

Notes:

This motherboard is infamous for having no cache. The "DCA" technology was a fraud by Octek (see here http://redhill.net.au/b/b-95.html) The Hippo VL is identical to the VL+ except having a LIF socket instead of ZIF. Hence the schema and settings of the VL+ were added here.
