| Tue Jan 29 1991 -by- MichaelE
|
||
|
|
| Redesigned installing installable drivers so additional drivers
|
||
|
|
| can be installed by adding them to setup.inf's [installable.drivers]
|

|
|
|
|

|
|
| Wed Mar 20 1991 -by- MichaelE
|
||
|
|
| Changed mmAddInstallableDriver to accept multiple VxDs.
|
||
|
|
| Changed and WriteNextPrivateProfileString to check if the profile
|
||
|
|
| being concatenated is already there.
