Checked out #Linux kernel v3.7.10 to see if I can strip it down enough to run on the 386 with 4MB of RAM in the Toshiba T5200. My plan is to do something very similar to what I did in my blog post where I targeted a 486 (https://www.insentricity.com/a.cl/283), but this time use LOADLIN.EXE to load the kernel from DOS since I don't have a working floppy drive.

No make tinyconfig on v3.7.10. That's going to make stripping it down a lot more work. #Linux #RetroComputing #VintageComputing

Setup a Debian 7 Wheezy docker environment to build in. But already running into compile problems which seem to be caused by lack of 386 support:

In file included from include/linux/irq_work.h:4:0,

             from arch/x86/kernel/irq_work.c:8:

include/linux/llist.h: In function 'llist_add':

include/linux/llist.h:160:11: error: 'boot_cpu_data' undeclared (first use in this function)

Looks like v3.3.8 was the last version that could be built for 386. After that there's some change that prevents the kernel from compiling. #Linux #RetroComputing #VintageComputing

Still can’t get my kernel to boot. Went and got the Slackware 1 kernel and used LOADLIN and that’s at least something! Maybe I should try to fix the floppy drive so I can do a traditional Linux install? #Linux #RetroComputing #VintageComputing

@fozztexx The reason for boot failure is right in front of you. This kernel doesn't support your hard drive geometry.
