Hi.

I've installed 2.2.5-R on my machine after a long break from FreeBSD.

I have a Dual PCI/IDE controller with a regular disk on wd0, and a 
Samsung CSR2030 ATAPI CD-ROM as secondary slave.  The other system
beginning with L is happy to find and use the CD-ROM, while FreeBSD 
doesn't seem to find wdc1, let alone what's connected to it.

When I boot, it seems that wdc1 is not found: dmesg from a -v boot 
includes the following excerpts

...
chip2 <Intel 82371SB IDE interface> rev 0 on pci0:1:1
	mapreg[20] type=1 addr=0000e800 size=0010.
	Primary IDE: enabled
	Secondary IDE: enabled
...
wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <QUANTUM FIREBALL ST3.2A>
wd0: 3079MB (6306048 sectors), 6256 cyls, 16 heads, 63 S/T, 512 B/S
wdc1 not found at 0x170
...

My kernel config includes the following

...
controller	wdc0	at isa? port "IO_WD1" bio irq 14 vector wdintr
disk		wd0	at wdc0 drive 0
#disk		wd1	at wdc0 drive 1

controller	wdc1	at isa? port "IO_WD2" bio irq 15 vector wdintr
#disk		wd2	at wdc1 drive 0
disk		wd3	at wdc1 drive 1

controller	wcd0
options		ATAPI		#Enable ATAPI support for IDE bus
options		ATAPI_STATIC	#Don't do it as an LKM
device		wcd0	#IDE CD-ROM
...

Any ideas?

And has anybody got a Samsung SCR2030 working with FreeBSD anyway?  (I note that the FAQ is a bit vague about which ATAPI CD-ROMs do and don't work.)
