Int 2F/AX=4502h

Microsoft Profiler (PROF.COM/VPROD.386) - SET SAMPLING RATE

AX = 4502h
BL = sampling rate for PROF.COM (0 < BL <= 13)
(01h = 8192/s, 04h = 1024/s, 08h = 32/s, 0Dh = 1/s)
CX = sampling rate for VPROD.386

Note: For PROF.COM, this programs the CMOS clock by setting BL+2 as the low four bits of CMOS register 0Ah. The interruption rate is 1 SHL (15 - BL) per second.
