|

|
; * Whenever an INT 2F call is made, sooner or later this function will
|
||
|
|
; * get control. If the call is actually for the redir, AH will be set
|
||
|
|
; * to 11h (MultNET). If it is any other value then we just chain it
|
||
|
|
; * along. Note that since there is no MINSES loaded in the NT DOS network
|
||
|
|
; * stack, then we need also to fake calls to MINSES. These are made through
|
||
|
|
; * INT 2F, with ah = 0xB8. We trap calls AX=B800 (network presence test)
|
||
|
|
; * and AX=B809 (network/redir installation test)

|
|
; * Install check 0
|
||
|
|
; * Assign operation 30
|
