MOL: summer of 68, 69 or 70

[Eric D]

Alright, since my English is quite a bit better than my Dutch here goes...

What has happened is that you updated your kernel from 2.4.22-2f to the 
2.4.22-2g kernel (possibly by running yum update or yum update kernel). A 
kernel is the most basic piece of software on your computer. It handles the 
task of gettting the computer up-and-running and basic input/output.

MOL 0.90.68 has its mol-kmods compiled for a different and older (pre-3.0.1) 
kernel (why it would be in the 3.0.1 updates is beyond me!).

MOL 0.90.69 (the one that comes with YDL) has its mol-kmod compiled for the 
SMP version of the kernel that ships with YDL, but YDL normally uses the 
single processor version of the kernel. This can be changed (as I found 
out).

MOL 0.90.70 doesn't have pre-compiled mol-kmod, you _have_ to compile it 
yourself no matter what!

In all three cases you can choose to re-compile (or compile) the mol-kmod 
files to have the mol-kmod file match the kernel version on your computer. 
Like I said before, you can find info on how to do this earlier in the week 
in this forum, at the URL that you originally pointed to, and at 
www.maconlinux.com mailing list archives for August (view the archives by 
Thread).

In one case (MOL 0.90.69) you can simply do a switch of the kernel, rather 
than fiddling with the kmods. I swapped the 2.4.22-2f kernel for 
2.4.22-2fSMP and my computer's perfectly happy _and_ MOL 0.90.69 works like 
a charm. I found the 2.4.22-f2SMP kernel in the /boot directory.

SInce I have to use OS 9 as my helper OS (for the OldWorld bootloader... if 
you're using ybin on a NewWorld machine there will be different instructions 
on how to replace a kernel) I took the vmlinuxBLAHBLAHBLAH2.4.22-2fSMP file, 
mailed it to myself (using GMail or Yahoo mail), booted in OS 9, d/l the 
file, moved it into System Folder:Linux Kernels (or something like that), 
and selected it as my kernel to use in XBoot, clicked Save and clicked 
Linux.

MOL ran for me once I got the configuration files working properly!

As for having 0.90.68 intalled. If you can't get mol-kmod recompiled, I 
discovered you can re-install 0.90.69 from CD. The 3rd CD contains the rpm 
for mol! Do a yum remove mol (and yum remove mol-kmods if necessary), then 
rpm -i mol installer file name

I copied the installer to my desktop but I imagine you can run it from CD by 
going to /dev/cd or something like that (can you tell I'm a newbie ;).

As for you running kernel version 2.4.22-2g, I don't know how to downgrade 
to 2.4.22-2f (well, a reinstall would accomplish that (and probably be 
quicker than figuring out how to recompile mol-kmods)). Your only solution 
now is to get mol-kmods recompiled (or downgrade to 2.4.22-2f and switch it 
with 2.4.22-2fSMP and install mol 0.90.69 from CD)
