In trying to reduced the size of the kernels, I went thru the make menuconfig and removed various options that it listed as being best to say N if unsure. I tested the changes on the systems I have available and it appeared to save about 1/2MB of each kernel, but have had a few users that noted that usb keyboards don't work. Changing back to the earlier build base solves the problem, so the update is mainly just the kernel updates plus the other changes.
Latest changes with 0.29
Release syslinux 3.73
Kernels 220.127.116.11 and above rebuilt
reduced size by about 1/2MB but usb keyboards stopped working.
Have started working with 3 students on a special project with
the main ideal of updating documentation to the current level
and develope a g4l-lite that includes only default kernel and
ramdisk.gz and tools to add g4l via grub4dos, grub, or syslinxu.
