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!
