Initial release.
BLCSET can be used from real mode to set the LCD brightness on a ThinkPad T430.
BLCINIT can be used from CONFIG.SYS so that it can be used before EMM386 or similar expanded memory manager is loaded:

DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\BLCINIT.SYS 01E7
DEVICE=C:\DOS\EMM386.EXE RAM

In both cases the only accepted/required parameter is the LCD brightness level in hexadecimal form.
On my T430 the levels are the following:

BLCSET 0045 - minimum level
BLCSET 01E7 - medium level
BLCSET 1155 - maximum level
