AX = 4B05h ES:BX = 0000h:0000h CX:DX -> task switcher entry point (see #02819)
Return:
ES:BX -> startup info structure (see #02822) or 0000h:0000h
Notes: Called by task switcher. Clients with instance data should hook this call, pass it through to the previous handler with unchanged registers using a simulated interrupt. On return, the client should create a startup info structure (see #02822), store the returned ES:BX in the "next" field, and return the address of the created structure in ES:BX. All MS-DOS function calls are available from within this call. This function is supported by Novell DOS 7 DOSKEY, with structure v3.00
