Refresh Cycle Enable
When disabled, the normal refresh cycle issued from SiS600 will be disabled. This
function is used by BIOS to perform SDRAM initialization, during which period
SDRAM can still be refreshed by programming register 57h bit 5. For normal
operation, this bit should be programmed with 1.
