[svlug] Problems Mounting Second CDROM ...

OS: Red Hat 5.2 (Apollo)

In the past, I have been able to mount my cdrom that was connected to my
sound card (Sound Blaster ISA PnP).  At this time, I had only one cdrom
in the system.  I was able to mount the cdrom by booting to Windows95
and performing a soft boot to Linux.  In my lilo.conf file, I had the
following:
append="hde=cdrom ide1=0x168,0x36f,10" so that Linux would probe the
device.

Now, I have two cdroms in my system; one is connected the hard disk
controller (bus0) and the other cdrom is still connected to the sound
card.  I have 2 devices on the primary bus (hard drive and cdrom) and I
have 2 devices on the secondary buy (2 hard drives).


Things I have tried:

1
Soft boot from Windows95
The following parameter was obtained from Windows95
cdrom =>  0x1e8,0x3ee,11

2..
I have created a sysbolic link to cdrom1
i.e
ln -s /dev/hde cdrom1
A sysbolic link cdrom currently points to /dev/hdb.  This will make
sense when you look at the output from dmesg.


3.
At boot time, I passed the following parameter to the kernel:
linux hde=cdrom ide2=0x1e8,0x3ee,11

I have included system information from dmesg, cat /proc/ioports and car
/proc/interrupts.  Messages to look at:
Dmesg reports that ide2: ports already in use, skipping probe
cat /proc/ioports does not show ide2 ???.
cat /proc/interrupts shows interrupt 11 is still free.

Thanks,
Phillip
