|

|
|
; This little utility simply installs InVircible's registration key onto
|
|||
|
|
; your hard drive. It is located on the last sector of the first cylinder
|
|||
|
|
; and is designated by the word 48A5h residing at the end of the sector.
|
|||
|
|
; After installing this, all current and future copies of InVircible installed
|
|||
|
|
; on that hard drive will be registered, or licenced rather.
