Delay Command

The delay command pauses further processing of OUT or InitCode commands by the boot code:

Delay Value

Parameter Value specifies the value loaded into register CX before the assembler code sequence

L1: LOOP L1

is executed. Value must be in the range 0..FFFFh. On an Intel 386EX at 25MHz, each loop iteration requires 11 clock cycles, which is approximately 0.44 microseconds. On a Pentium 133MHz, we have measured one iteration to take about 0.038 microseconds.

The use of the Delay command may be required for chipset initializations to become effective (e.g., RAM refresh, etc.).
