32-bit version won't boot on 64-bit machine [Solved]

[chrispop99]

Apologies if this has been mentioned and I missed it.

I have some core i5 (64-bit) machines that have always been able to boot 32-bit versions. This was the case up to MX-21.x. They won't boot 32-bit versions of MX-23 however - neither Fluxbox or Xfce.
Has something changed that can be easily reverted? It will limit testing for me as one of two 32-bit machines has died.

Sounds like a feature, you should use 64-bit on 64-bit machines... but otherwise I have no idea, maybe a kernel option?

I test here, so need to be able to boot 32-bit versions. Multiple machines speed up the process, and my one remaining 32-bit machine might die.

... You should try first with an old kernel (ex: 6.1.xx) ... what is your current version kernel for the X32 snapshot ?

The 32bit isos are supposed to boot on 64-bit systems, at least when selecting CSM/MBR/BIOS-BOOT mode. UEFI-32bit booting on 64bit UEFI may have issues, depending on UEFI firmware.

I'm not UEFI booting with these.

I should have mentioned that this is booting live from USB.

I'll have to check that. I did test the 32 bit xfce release on a 64 bit netbook. besides needing to disable UEFI, I didn't have any issues.

It's definitely hardware dependent.
An MX23.1 32bit iso boots just fine on this old 64bit box

I'm typing this on it now.
But no such luck on the AMD Ryzen3 HP box in my sig. Can get to grub but can't even boot in single mode.

Was the installation performed on a dos or gpt partiontable. If gpt, best to have as first a 1MB bios_grub partition setup,
otherwise bios/mbr-grub loader may have difficulties to find it's core.img loader on the drive.
