ISO: 2018.09.01

In the latest ArchLinux ISO the "Hardware Information (HDT)" in the boot menu is broken.
Of course this only happens when booting via BIOS, since UEFI doesn't provide this feature.

Steps to reproduce:
1. Boot ArchLinux ISO via BIOS (NOT UEFI!)
2. Select menu item "Hardware Information (HDT)"
3. Get "Undef symbol FAIL" error (see attached Screenshot)

I managed to reproduce this on a Sony VAIO (VPCEB4J1E) and VirtualBox.
These are also the only things I tried it on.
Very confident that this is an issue on every other device and VM-Software.

This task depends upon

I do not see these changes got landed official git repo yet. Please work with upstream on reviewing/merging the change and then we'll get it to Arch package as well.

This is the same issue that FS#57638

Debian also had this issue and their patch has worked for me to boot Syslinux's HDT.

Thank you for the pointer to the debian patch. I brought it to Arch repo and syslinux-6.04.pre2.r11.gbf6db5b4-1 is available in [testing] now. Could you please verify if it works correctly?

The HDT seems to work correctly in the testing package.

efi64 variant still fails. When booting hdt.c32 I get this:
Undef symbol FAIL: pow
Failed to load libgpl.c32
Failed to load COM32 file hdt.c32

Sorry for letting this slide. I have used this recently and it definitly works now.
Requesting closure.
