|
> You build MILO
|
|
seperately from the Kernel. As MILO requires parts of the kernel
|
|
to function (for example interrupt handling) you must first
|
|
configure and build the
|
|
kernel that matches with MILO that you want to build. Mostly this
|
|
means building the kernel with the same version number.
|
|
So, MILO-2.0.25.tar.gz will build against linux-2.0.25.tar.gz.
|
|
MILO <TT
|
|
CLASS="LITERAL"
|
|
>may</TT
|
|
> build against a higher version of the kernel, but there
|
|
again it may not.
|
|
Also, now that ELF shared libraries are fully supported, there are two
|
|
versions of the MILO sources.
|
|
To build under an ELF system you must first unpack the standard MILO sources
|
|
and then patch those sources with the same version numbered ELF patch.
|
|
In the remainder of this discussion,
|
|
I assume that your kernel sources and object files are stored in the
|
|
subtree at <TT
|
|
CLASS="LITERAL"
|
|
>/usr/src/linux</TT
|
|
> and that the linux kernel has been fully
|
|
built with the command <TT

If you can (and want to), then type "y", otherwise "n".

All of the standard, pre-built, MILO images include serial port I/O using COM1.</P
