CorePure64 17 won't boot on Dell Pro Max with Intel Core Ultra 5

[catselbow]

Apparently, no version of CorePure64 will boot on a new Dell Pro Max workstation (it has an Intel Core Ultra 5 processor, for what it's worth).  For example, when booting the stock, grub-based TinyCorePure64-17.0.iso from a USB drive the computer hangs with a black screen immediately after tc, tcw, core, or corew is selected fromt the boot menu.  The computer is completely unresponsive and doesn't respond to ctrl-alt-del. It has to be power-cycled.  I've tried kernel parameters like nomodeset, noapic, nolapic, acpi=off, but none of these change the behavior.

If I boot a custom, syslinux-based USB drive, it gets to the point of writing "Loading /corepure64.gz... OK" and then hangs.

A Fedora43 live image does boot without any problems.  Any suggestions would be welcome.  Thanks.

I wonder if this is due to a uefi incompatibility - does it boot from a CorePlus iso in legacy bios mode?

Hi catselbow
If your system is using a dedicated GPU, try changing it
in the BIOS to the CPUs graphics hardware.
