Int 2F Fn 8002 - Cs_tsr Specification - Get Process Block By Process Han [t]
AX = 8002h
BX = process handle for TSR (see AX=8001h"CS_TSR")
Return: ES:DI -> process block for specified TSR (see AX=8000h"CS_TSR")
unchanged if no match for process handle
Note: This function is used to allocate a process handle when the TSR
installs itself, by setting ES:DI to point at something other than
a CS_TSR process block's signature string and iterating through the
possible process handles (0001h to FFFFh) until ES:DI is returned
unchanged
