>Environment:
I'm using a pentium motherboard with a SiS 5513 PCI IDE controller and on
wdc1 I have an ATAPI CDROM drive, (Creative Labs Infra1800 12speed very new
with a remote control that will run Webbrowsers under windoze 95 !!)
here's some spurious info from bootup :
...
pcibus_setup(1): mode 1 addr port (0x0cf8) is 0x8000f800
pcibus_setup(1a): mode1res=0x80000000 (0x80000000)
pcibus_check: device 0 is there (id=55111039)
Probing for devices on PCI bus 0:
configuration mode 1 allows 32 devices.
chip0 <generic PCI bridge (vendor=1039 device=5511 subclass=0)> rev 0 on pci0:0
chip1 <SiS 85c503> rev 1 on pci0:1:0
pci0:1:1: Silicon Integrated Systems, device=0x5513, class=storage (ide) int a irq ?? [no driver assigned]
map(10): io(01f0)
map(14): io(03f4)
map(18): io(0170)

>Description:
I have tried 2 other CDROM drives and the same thing happens on startup,
one out of four times I get :
wdc0 at 0x1f0-0x1f7 irq 14 flags 0x80ff80ff on isa
wdc0: unit 0 (wd0): <QUANTUM TRB850A>, 32-bit, multi-block-8
wd0: 810MB (1660176 sectors), 1647 cyls, 16 heads, 63 S/T, 512 B/S
wdc1 at 0x170-0x177 irq 15 flags 0x80ff80ff on isa
wdc1: unit 0 (atapi): <CREATIVE CD1220E/ec1.02.>, removable, dma, iordy
wcd0: 171/2062Kb/sec, 240Kb cache, audio play, 255 volume levels, ejectable tray
wcd0: 120mm audio disc loaded, unlocked
and the rest of the time I get :
wdc0 at 0x1f0-0x1f7 irq 14 flags 0x80ff80ff on isa
wdc0: unit 0 (wd0): <QUANTUM TRB850A>, 32-bit, multi-block-8
wd0: 810MB (1660176 sectors), 1647 cyls, 16 heads, 63 S/T, 512 B/S
wdc1: not found
I'm not sure precisely what it says for the not found line, but it's just
the standard "I can't find this thing here line"
Occasionaly wdc1 is found but the CDROM drive isn't, but that is very rare
and usually boils down to a bad cable or somesuch... but not always =)
>How-To-Repeat:
I have absolutley no idea how to repeat the problem other that
restarting the computer and watching it fail to find wdc1, however I have
noticed that if I actually cold boot my system it seems _slightly_ more
likely to find the controller than after a warm boot.
>Fix:
I'll try 3.0 but I'm confused.
