DOS ain't dead

Device drivers: Changing the attribute word at install time? (Developers)

tkchia,

Thank you, that makes more sense. If I understand it correctly, the device driver is compressed except for the unpacker, which should run when DOS calls the device driver init routine.

In that case the attribute word is still in the same location and can be modified by the unpacker installer routine.

It sounds like the comment about OpenDOS above is specific to OpenDOS, and not a general limitation of MS or PC DOS.
