6 Technical Description
6.1 ISA Bus Support
6.1.1 Display Adapter Card Support
6.1.2 Expanded Memory Manager
SED1374
X26A-G-005-01
This board has been designed to support the 16-bit ISA bus environment and can be used
in conjunction with either a VGA or a monochrome display adapter card.
There are 5 configuration inputs associated with the Host Interface (CNF[3:0] and BS#).
Refer to Table 2-3: “Jumper Settings” and Table 5-1: “Host Bus Interface Pin Mapping”
for complete details.
When using the SDU1374B0B in conjunction with another primary Display Adapter (VGA
or Monochrome) the following applies:
ISA or VL Bus VGA Display Adapter
When the SDU1374B0B board is used with an ISA or VL Bus VGA display adapter, the
VGA card must have a 16-bit BIOS to prevent conflicts during 16-bit accesses
(MEMCS16#). If an 8-bit VGA adapter card is installed in the system being used, it must
be removed and the screen display routed through a COM port to a terminal display device.
PCI Bus VGA Display Adapter
All PCI based VGA display adapters can be used in conjunction with the SDU1374B0C
board.
Monochrome Display Adapter
All monochrome display adapters can be used in conjunction with the SDU1374B0C
board.
If a memory manager is being used for system memory, the address range D0000h to
DFFFFh must be excluded from use as this range is used by the SDU1374B0C.
