There is three jumper named J18, J19, and J21 on X10SLH-F motherboard, but your manual did not mention what they are for. Can you tell me what are the functions of those Jumpers?
Jumpers J18 and J19 are for VRM code update, and they are for manufacturing used only and should not be changed. Jumper J21 is for NIC EEPROM refresh enabling, the default setting is disabled.
