I want to use Slackware on my ancient i486 DX to use my 5.25" Floppy with TRS-80 Emulator.

I was happy to see, that Slackware still supports i486. I just tested the installation from slackware-14.2-install-dvd.iso with qemu-system-i386 -cpu 486 ...
I can successfully boot the iso with boot-parameter: huge.s and uname -a shows me a 486 kernel.
But package installtion from iso failed with the setup utility, because it tries to install x86_x64 packages instead of i486.

The setup tool gives error messages on every package like this:
ldconfig: ../sysdeps/x86_64/cacheinfo.c:262: handle_intel: Assertion 'maxidx >=2' failed.
/usr/lib/setup/installpkg: line 271: 2769 Aborted

Can someone help me? Or is there an optional way to install slackware on i486 Computer?

Hello RuebeSoft & welcome to LQ. Your error was
Something in there is 64bit. Are you running the install from a 64bit PC? You can check the ldconfig with

file /path/to/ldconfig

EDIT: 32bit packages have i486 in them; 64bit have x86_64 in them.

Hi, unfortunately the file command is not available with the ISO boot system.

But when I execute /sbin/ldconfig I get this error:
ldconfig: ../sysdeps/x86_64/cacheinfo.c:262: handle_intel: Assertion 'maxidx >= 2' failed.
Aborted.

And uname -a gives me:
Linux slackware 4.4.14 #2 Fri Jun 24 15:28:18 CDT 2016 i486 GNU/Linux

In the meantime I found a solution here: https://www.linuxquestions.org/quest...mx-4175609184/

I did what Didier explained:

Start the machine with the installation media inserted, then as soon as logged in as "root" type:
Code:

lsblk -o model,name,size,fstype # to check the installed system's root partition's. Let's assume it's hda1.
mount /dev/hda1 /mnt
ROOT=/mnt removepkg glibc-solibs
ROOT=/mnt removepkg glibc
wget http://ftp.slackware.com/pub/slackwa..._slack14.2.txz
wget http://ftp.slackware.com/pub/slackwa..._slack14.2.txz
installpkg --root /mnt glibc-2.23-i586-4_slack14.2.txz
installpkg --root /mnt glibc-solibs-2.23-i586-4_slack14.2.txz
umount /mnt

Then, remove the installation media and reboot.

Hint: To get wget working on ISO boot you have to execute "pxesetup" to setup a network connection first.
