LILO & other problems

[Anders Karlsson liv se]

I have some knowledge of NT/2000 but i'm kind of new to linux and need some help.
Is this the right place ?
 Installed RedHat 7.0 with LILO on MBR and this worked fine but now it fails to boot.
All i can see know att boot time is LI (two first letters) and there it stops.
I probably messed this up somehow.
Have a boot floppy though, but it takes a LONG time to boot this way and i of course want to reinstall it on MBR.
Tried lilo command when linux finally started up but that didn't help. / is mounted on /dev/ida/c0d0p5  and /boot on /dev/ida/c0d0p2
The first partition (seems to be /dev/ida/c0d0p1) contains the Compaq configuration utility.
 Also, i have added a CPU but i guess i have to make the OS aware of it somehow since it doesnt show in /proc/cpuinfo.
Do i have to recompile the kernel or is this configurable ?
If i must recompile, how do i do this ?
 Also, should i use the 2.4 kernel instead of the kernel included ?
If this is the case what other modules do i first need to update to make it work ?
 Also i found out that gcc 2.96 that is shipped with RedHat 7.0 is a nonstable release (!?) and that it would be impossible to recompile the kernel with this version anyway.
Is this true and if so how do i "degrade" my gcc version ?
 Also, when (if ?) i get this working, is it possible to dedicate one of the CPU:s to a specific process ?
 Also i got Samba and Apache working perfectly but the linuxconf web interface does not.
Found an update (xinetd-2.1.8.9pre11-1.i386.rpm) that should take care of this but i still fails.
Ofcourse added the line "disable = yes" to "disable = no" in /etc/xinetd.d/linuxconf-web and restarted xinetd but it still fails.

Also, how do i set the Interface NIC to 100Mb - full duplex ?
The Cisco switches here is strictly configured like this and it does NOT work with auto-negotiate settings on the NIC.
This seems to be the default settings in linux though and changing this setting is a very simple task in NT.
Downloaded source for my NIC (Intel PRO/100) compiled it and used modprobe e100 e100_speed_duplex=4 and this works fine, but since i do not know where to add this to make the driver load properly when the system is started, i cannot finish the job.
 As i mentioned i'm not a linux wizard so excuse me if these questions are trivial.
Must comment that while i was copying 13 GB of data to this server, a netspeed test towards it gave me a result 50% better then the same test towards my NT4 server.The NT server was IDLE at the time...
Remarkable.
