And another plan is to review my patches for 3.7.10 kernel, because it's just bunch of hacks and I still learn much more from work on them. Basically, main goal has been: make machine with 3COM card with lanworks proprietary boot rom b

X would be great addition. Someone here point me to linux distro for 486 machines with working X. However, I don't think it will be bootable from network with full X window and window manager support. So I need to find a way how to use

Maybe and maybe another hacks and also not compiled support for 486 cpus. This hack is invoked only on CPUs, which doesn't support cmpxchg instruction. For example, 486 DLC from Cyrix is basically 386 with i486 instruction set but I&#x

Great! But don't expect much for now. But personally, I'm happy with result, because I'm able to deploy dos machines with bigger HDDs (with help of XTIDE bios - still playing around) or just put dos images to HDDs via network

Not all i386 in name are real 386. Sometimes they think about i586 or i686 (which is way how to mark generations of CPU). From provided page: Processors All CPUs compatible with the Intel Pentium or later, with Intel-compatible hardware flo

Hi. I don't know for now. There is ton's of issues while switching to protected mode (ipxe for example: https://github.com/ipxe/ipxe/commit/bc35b24e3ebd2996b2484b7f... ). It just stuck when I select

Old distribution with old userspace :). I understand that it looks hard. But you can download precompiled kernel and initrd. Yeah, there is only busybox for now.

But this emulates 486 systems and not precisely. For example, endbr32 instruction is not a problem under emulation but it's real issue on real i386/i486 hw. Simply because real 386/486 cpus doesn't support multi nop inst

Yeah, but 486 is not 386. Nix is used to preserve development environment of linux kernel. Without nix, setup would be much, much more complex. Thank you for info about avc-edge-linux. Going to take a look :).

It's easy. There seems to be nothing directly support i386 (I mean: real 386 chip) with latest supported kernel version (as I know) and newest busybox. i386 doesn't support cmpxchg instruction for example and I'm not able (ma
