Please note that a i486 computer(motherboard) limits the capabilities of the CPU.Those computers could not recognise a harddisk larger then 500MB. A driver has to be loaded at boot time for it to recognise a CDRom drive.They could not boot from a CD (need something like Smart Boot Manager). The computers did not have USB ports (unknown at the time). The CPU lacked PAE. RAM was also a limitation. I am not sure if there were any MoBos capable of carrying more than 32 MB.

However the original request was about a Pentium which overcomes some of the above limitations.

It would be more complicated than that. This is a change that Linux implemented to the kernel itself, so what you're suggesting would require using a much older version of the kernel to build in i468 support. That cascades down by require older libraries and compiler to build it. It would also require the use of older versions of services that'll run on the older kernel and a complete rebuilding of all the applications to work with older libraries, kernel and services. This seems like a lot of work to use a machine that's well over 25 years old. Alternatively, I suggest using TinyCore since it does still support i486, but comes with the above mentioned limitations and issues I mentioned above

Do you know any way to emulate a i486 computer? That way I could try to do build a Linux kernel that works on that machine. Linux still supports i486 up to this date

I saw thing like this a time ago when projects ended [45]86 processors support. Maybe is the case.

In my limited knowledge on subject, solution is recompile slitaz kernel on your machine.
In any case, I don't know how to do it. Or if Slitaz has support for Pentium or it's equivalents, like K5-6's.
Developers should have some instructions.

Gentoo's wiki should give you directions, 'cause it supports i486.

In my opinion a complete rebuild of the system would be requird. My suggestion is to use a decent modern machine to build a cross-compiler that targets i486 and use that to build Slitaz; that way you could benefit from the better performance of a modern machine.

Sorry but I can't help beyond this.

Dear Slitaz community,

I try to get Slitaz (Rolling, lowRAM) to run on an ancient Pentium-MMX (P54M) with just 64 MB RAM.
problem: cmov instruction missing, boot aborts (in Virtualbox it otherwise runs on 64MB plus some swap)

Now I need help in one of following ways:
(1) Forum registration does not work with several accounts/email addresses --> can someone help?
(2) Can I somehow ( i.e.: how? where do I find docu/tutorial) cook a Slitaz-lowRAM-ISO with a 486 or Pentium-1-compliant kernel? If at all - this here is the right distro for such ancient hardware!
(3) Or - is there an archive somewhere were I could get a rolling loRAM ISO from a time when such P-1-compatible Kernels were around?
PS: 5.0-RC3-ISO does not boot due to beeing not loRAM (?)

Thanks already for help!

Torsten
