People keep mentioning windows XP, but iirc it requires 64MB minimum RAM which can be a bit high for 586-era machines.

I still technically count it because most 586 era machines should be able to get that much RAM. 64MB was a pretty common ceiling during the late 486 era. Even my 1995 NEC Ready 9522 has a 128MB Memory ceiling, but from the same brand and opposite end, my Versa P/75 tops out at 40MB.

Well these can also be useful, even if you weren't using them as your daily workhorse OS.
For example, consider the emu devs. These niche-OSes provide an alternative codebase to test the emulator against.

maybe you could set a similar machine up in pcem as a vm to test things out but im not sure if disabling dynarec to run win 7 would give you accurate results.

The main issues I see with trying to run modern os on a 586 is not so much if it can run. Anything that is running on it has to be compiled to run on 586, like the web browser. Fining a update web browser that will run on 586 is pretty challenging. Normally you would need at least MMX. And from what I read AMD mmx implementation in socket 7 isn't complete at that.

Doesn’t matter. List should be of ones that work and last version that does work even if that is the current version

I have 256 in one 586 and 512 in another. Ram doesn’t matter for this list that’s a separate issue.

I’ve totally struck out trying to find a browser that runs on windows. Open to suggestions. I think linux may be an option but forgot to try it when I had it loaded.

  • CentOS up to EL6

EL6 requires PAE, EL5 requires i686.
Earlier versions are somewhat inconsistent. EL4 should work on i586 based on https://wiki.centos.org/FAQ/CentOS4#What_is_CentOS_4.3F and the list of packages from https://archive.kernel.org/centos-vault/4.0/o … 86/CentOS/RPMS/ where there are kernel packages for i586 and i686.
However, EL3.1 https://archive.kernel.org/centos-vault/3.1/i … 86/RedHat/RPMS/ and EL2.1 https://archive.kernel.org/centos-vault/2.1/f … 86/CentOS/RPMS/ only have kernel packages for i686 and athlon.

Interesting exercise but that's well off the beaten path, especially as the table indicates it only works with either non-MMX i586 CPUs or non-PAE but SSE2-supporting CPUs. CentOS 7 is officially x86_64 only (matching upstream RHEL 7), with the i386 version (with i686 kernel) as AltArch. That means no 3rd party repos like EPEL (there is an unofficial, unsigned version) or rpmfusion.

list of browsers. That will run on windows 586. I was under the original assumption that you knew this all along. Thats why I kept scratching my head. Because both of these browsers are pretty modern.

np, theres another one Kmelon with goanna engine. I forgot about it. should be able to find it.

The main thing with the intel nics is the interupt moderation rate. The lower that is the more CPU it uses but its faster on fast cpus, the higher it is the less. There is a Extreme setting at least on the MT adapters which is max. It does lower CPU utilization in a measurable way.

Just like 3 com there is offloading of receiving and sending tcp/ip checksum those should be on by default.

last there is the send and receive transmit discripters. Lower the value it uses less ram but transmit speed is also slower, higher the opposite.

for a 586 Id probably put it on extreme setting, memory usage you will have to play with. Guessing on minimal which is 256, but it goes to 2048 max.

Probably I wouldn't put it on 1000 mbs setting and Id lower it to 100Full duplex even on the gb adater on a 586

system has 512mb of ram so that will be handy.
