1747-UM001A-US-P - March 2000
Defining System Settings 5-9
Using Memory Managers If you are using a memory manager, you must exclude from the memory
manager the memory:
•
used by the I/O scanner dual-port memory, as defined by the open
controller API software or as reported by the open controller diagnostic
utility.
– 1747-OCE: The recommended memory is C800-C9FF
– 1747-OCF: The memory window is automatically allocated by the
PCI BIOS
•
assigned to the 1747-OCKTX, -OCKTXD module, if you are using one,
as reported by the
ocpci
or
ocpci_nt
utilities (see chapter 8).
•
allocated in the
\cardsoft\config
utility (the default is D000-DFFF)
if you are using CardSoft services. See the CardSoft documentation that
comes on disk with 1747-OCPCM2.
Operating System
Considerations
The following table lists system considerations for some of the operating
systems you can install on an open controller.
Table 5.D
Operating system considerations
For this operating system: Considerations:
DOS and Windows 3.x
The SystemSoft

card and socket services for DOS/Windows 3.x,
version 3.1, limit an open controller system under DOS or Windows 3.x to two
1747-OCPCM1 modules (4 slots).
SystemSoft CardSoft card and socket services come with the 1747-OCPCM2
kit. For more information about configuring and using these services, see the
documentation that comes in the 1747-OCPCM2 kit.
Windows 95 You can install as many as two PCMCIA modules (four slots) per open controller
chassis.
If you use 2 PCMCIA interface modules, define IRQ 3-11 as ISA/EISA. Leave INT
14 defined as a PCI/PnP interrupt (for the primary master drive). If you use 2
PCMCIA interface modules and you have a 1747-OCKTX, -OCKTXD module in
this same open controller chassis, all the channel jumpers must be set for ISA/
EISA interrupts.
Windows NT Windows NT limits itself to one 1747-OCPCM1 module.
Not including IRQ 14 and IRQ 15, you must define one PCI/PnP interrupt for each
1747-OCKTX, -OCKTXD interface module and for each PCMCIA interface
module. If you want to use IRQ 3, IRQ 4, or IRQ 7 for 1747-OCKTX, -OCKTXD
channels or PC Cards, you must disable the COM port within Windows NT.
Windows NT 4.0 does not support Plug and Play (PnP), so it has no way to detect
that BIOS assigned an IRQ to a PCI/PnP device. Take care to reserve in BIOS any
IRQ that is used by an ISA/EISA device (such as the open controller scanner, an
Ethernet communication card, etc.) so that the BIOS does not assign the IRQ to a
PCI device.
