Tech Tip
TECH TIP NO.: TT82.002
PRODUCT: Series 82 Super Voyager VLB-II
DATE: September 17, 1993
ORIGINATOR: Vivek Saxena
RELEASED BY: Documentation Control
SUBJECT: Change to SMC665
The SMC661 I/O chip is being replaced with the SMC665 I/O chip. Serial ports
in SMC665 are 16550 compatible.
At the present time there are two ways to enable these ports as 16550:
1. Microsoft Windows 3.1 programs these ports automatically as 16550.
2. For a DOS environment, a utility (16550.EXE) is available from
American Megatrends Tech Support. This utility, which can be downloaded from
the BBS, will enable 16550 UART support.
Two jumpers at J25 and J33 have been added to the board; these jumpers are
reserved for the future use of American Megatrends.
