Settings for external components (e.g. MobiDock, PC card):
Function I/O address IRQ DMA

IDE-Hard disk controller in the
MobiDock (PCI)
170h - 177h, 376h IRQ 15
Internal

controller "Adaptec
AIC7850" in the MobiDock
Automatically
recognized
Shared IRQ
Max. two PCI slots in the MobiDock
(PCI to PCI Bridge)
and defined! Shared IRQ
Max. two ISA slots in the MobiDock
(PCI to ISA Bridge)
a) PnP-ISA: is automatically recognized
and defined (no shared IRQ)!
b) ISA (without PnP): depends on the
card setting!
PC card
(PCMCIA cards):
max. 1x TypIII or 2x TypII
•
I/O cards (modem, network board,
COM, SCSI etc.)
•
memory cards (e.g. SRAM,
FLASH)
•
ATA cards (e.g. Harddisk,
Sundisk)
PC cards require an IRQ (
no
shared
IRQ!), I/O addresses and/or a memory
area and possibly DMA.
(see also the documentation on the
PC card).
BIOS SETUP
PnP = Plug and Play
Shared IRQ:
Several PCI components can
share
one
free ISA-
IRQ
(assignment of the IRQs is automatic).
Conflict situations with ISA cards can be prevented under DOS/WfW with the "ISA configuration utility"
disk, which you created using the batchfiles in the directory
/PROGS/DISKS
(IRQ, DMA, I/O address,
etc. are reserved for the ISA card and are therefore no longer available for the PCI bus!).
Under Windows 9x you can change the resource contentions manually with the "Device Manager".
