No!lilo is not necessary if ur using loadlin.but I recommend
using lilo instead of loadlin.it saves you boot time.booting params if any
can be given to loadlin itself.give them at the end of the loadlin command.

this dir is used by the ppp daemon to store config and other info.the pppd
package will automatically create it.

u got it right.d=dir,r=read,w=write,x=execute, for owner of file,then next
three is for woning group and the last 3 is for others.the remaining no of
references,owner,group,zise,mod date stamp etc.u seem to be very curious.RTFM
see the man/info pager.Thats where u can learn all things.

chmod,chown,chattr etc.use these commands.

the program is to be set to run with effective UID(user id) as the owner of
the filei.e even if anyother user runs the file,the system will consider that
the owner(root) is running that file.so the program has the effective rights
of the owner.again RTFM see the man pages for chmod etc

UMSDOS?that is a filesystem driver.
you can use dosemu,setit up to run dos(real MS DOS),or a dos clone like
freedos.and runfoxpro inside it.
I have also heard of a few applications like flagship which can use foxpro
and clipper .dbf database files.

it depends on what is the definition of an OS.the kernel is the OS.but
without userland programs what is a kernel?
but linux , per se is only the kernel of the OS.it combines with other gnu
utilities, and other programs to form a complete OS disrtibution.
