Hi,
Just a simple question on the extract from FreeBSD installtion notes.
be configured as follows: (Note: IRQ 9 is the same as IRQ 2
on ISA/EISA based machines)
Device Name Port IRQ DRQ Misc
------ ---- ---- --- --- ----
Floppy Cntlr. fdc0 0x3f0 6 2
Std. Hard Disk Cntlr.
wdc0 0x1f0 14
AHA-154x SCSI Cntlr. 0x330 11 5 [kcopy-ah-floppy]
AHA-174x SCSI Cntlr. automatically configured [kcopy-ah-floppy]
BT742 SCSI Cntlr. 0x330 12 [kcopy-bt-floppy]
UHA-14f SCSI Cntlr. or
UHA-34f SCSI Cntlr. 0x330 14 5 [kcopy-bt-floppy]
(In FreeBSD GAMMA and before, UHA was on IRQ 11)
SCSI Disks sd[0-2] automatically configured
SCSI Tapes st[01] automatically configured
SCSI CD-ROMs cd0 automatically configured
Serial Ports com0 0x3f8 4
com1 0x2f8 3
com2 0x3e8 5
^^^^^^^^^^^^^^^^^
com3 0x3f8 9
SMC/WD Ethernet or
3COM 3c503 ed0 0x280 5 iomem 0xd8000
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I have all of the IRQ 2(9),3,4 and 5 used up for 4 COM ports, and I
will like to use 3c50c as well, can I still share IRQ 5 between com2
and 3c503 ? 3c503 only has IRQ 2,3,4 and 5 as selectable IRQ only!
Thanks in advance and email replies please!
