mroe than 4 serial ports

[wolfman8k]

I have a US robotics cp5310 internal pci modem that is on com5. I succesfully used it and Mandrake 8.1 and slackware 8.
But I can't get it working in debian.

I made a fresh install of debian with very few packages. Then I installed the kernel-package and kernel-source 2.4.18 package. Then I compiled the kernel with the "enable support for more than 4 serial ports" option. But when I execute as root:

setserial /dev/ttyS4 .....

It tells me that there is no such file /dev/ttyS4

when I do:

ls /dev/ttyS*

I get

ttyS0
ttyS1
ttyS2
ttyS3

Did I do something wrong? I should have much more then that(up to 7 or 8).

Thanks

Did Mandrake and Slackware both require ttyS4 and if so, did that device already exist or did you have to manually create it?

Have you tried using ttyS0-3? I've heard/read that sometimes Linux says com5 where in fact it is actually using com1-4.

If all else fails, you can try creating your own.

mknod -c /dev/ttyS4 4 68

I'm not sure of the syntax or 4 + 68.

I figured out what the problem is. I'm not running the kernel that I compiled. I know this because the login prompt says Linux 2.2, and I compile Linux 2.4.18.

I followed the instructions here (http://www.debian.org/releases/stable/i386/ch-post-install.en.html)

I didn't edit lilo.conf at all after following the instructions. Should I? I think it did it automaticly because When I press tab at the lilo prompt I see Linux and LinuxOLD. Maybe I always had that...

What do I do to use the kernel that I compiled???

thanks

[mdwatts]

Make sure the new bzImage (or whatever you named it) is in /boot and the initrd (if you use an initial ramdisk) is also in /boot.

Next add a section to /etc/lilo.conf for the new kernel and then run /sbin/lilo to write the changes.

Ok, I'm pretty sure I know what's going on...
This is what I get when I boot the system:

Debian GNU/Linux 2.2 jack tty1

jack login:



Notice the bold parts.
First of all, it starts out loading the 2.4.18 kernel that I compiled. It even correctly detects my modem on /dev/ttyS4.

Now something strange. It tries unsuccesfully to load modules for vfat, my sound card and nvram. It shouldn't do these because they are compiled directly in the kernel(I know this because you can see that it succesfully initialized them before that). Later, it complains about the System.map-2.4.18 file being bad. This is what I think is the major problem. Maybe, because it couldn't use this, it used the previous one and therefore tried loading the modules and that's why it says Debian GNU/Linux 2.2 at the end.

If I am correct and my System.map-2.4.18 file is messed up, then how do I fix it?

thanks

[mdwatts]

Whenever you compile the kernel, a new System.map is created in /usr/src/linux-<kernel version>.

Did you copy the new System.map to /boot and rename as i.e. System.map-2.4.18?

If the previous kernel had vfat, es1371 and nvram configured as modules and now you have built them into the kernel, you will need to edit /etc/modules.conf or whatever your distro uses and comment out the lines that are trying to load those modules.
