[Multiboot WinXP 64-Bits & 2003 Server SP1]

SETUPLDR.BIN is from two parts. I test "boot" part (first 20080 B in SP1) with SETUPLDR.EXE from SP1 directory and with SETUPLDR.EXE from W2K3 RTM. It always work, but only with unmodified exe file = "boot" check EXE CRC.

SETUPLDR.EXE from SP1 has same size as SETUPLDR.EXE linked to SETUPLDR.BIN (starting byte 20081h)

BUT: same code, but only debug text is different!!

Comparing files setupldr.exe and SETUPLDR_LOADER.EXE

00000120: 50 26 <- CRC?

00000121: 7F 63 <- CRC?

00039210: 25 50 <- ???
