32-bit CentOS

It appears that CentOS 7 was the last one with a 32-bit version. I'm
trying to install it on an older laptop and having some trouble. I have
CentOS-7-i386-Everything-1810.iso and have verified it. Using either dd
or mediawriter to put a copy on a 16 GB thumb drive seems to work. But
then the laptop reports, "no boot image found". Note that the first 32 KB
of the iso is all zeros, meaning that there is no MBR or partition table
included.

According to the 0_README.txt on the CentOS mirrors, the Everything ISO,
"contains the complete set of packages for CentOS Linux 7. It can be
used for installing or populating a local mirror. This image needs a
16GB USB flash drive as it is too large for DVD isos... You can burn
these images to a DVD or 'dd' them to a USB flash drive. After the boot
media has been prepared, boot the computer off the boot media."

Does anyone know what I don't understand about this procedure?

Can you post the exact command you used with "dd"?

(How old is this "older laptop"? Debian is worth trying on older
machines; it can be just as light as distributions specifically
designed for old computers.)

I tried to resurrect a 32-bit desktop with a Pentium 4 processor by
installing CentOS 7 32-bit version. Everything installed OK, but after
the first boot, the performance was unusable. And, the X11 would
crash repeatedly. CentOS 7-32 is completely useless.

Then, I tried Ubuntu 16-32 with the Gnome desktop. No crashes, but the
performance was unusable, although much better than CentOS 7-32.

Then, I tried Lubuntu 18-32, and I have a usable system now. Lubuntu is
Ubuntu with a light-weight desktop designed for computers with limited
resources.

I have also installed Xubuntu 12 on a laptop with a Pentium M processor
(pre-PAE capability for extended memory addressing). It performed
acceptably. Xubuntu is another light-weight Linux with the XFCE desktop.

CentOS will not be good choice of system for this case. Linux grows in
its demands to hardware rather fast. Not as fast as MS Windows does (I
remember when 2000 was released someone stuck "bloated pig" to it ;-)

Much better choice would be FreeBSD (or any of BSD descendants, e.g.
netbsd).

I hope this helps.
