Interrupt 0F8h  Set Shell Interrupt (OEM)  

Set OEM handler for Int\21 calls from 0F9h through 0FFh

entry AH 0F8h

DS:DX pointer to handler for Functions 0F9h thru 0FFh

note 1) To reset these calls, pass DS and DX with 0FFFFh. DOS is set up to

allow ONE handler for all 7 of these calls. Any call to these handlers

will result in the carry bit being set and AX will contain 1 if they are

not initialized. The handling routine is passed all registers just as

the user set them. The OEM handler routine should be exited through an

IRET.

2) 10 ms interval timer (Tandy?)
