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.

mostly for future thread visitors i would reference @Juanito from circa 2015

I just tried a dell latitude e7640 with 13th Gen Intel Core i7-1365U and it booted CorePure64-17.x, albeit with several acpi errors.

Unfortunately, this computer is "legacy-free".  uefi is the only option.

The machine only has on-board graphics: Intel Corporation HD Graphics 630 (rev 04)
It's using displayport (the only option)

I've used corepur64 for a long time on a lot of other machines, including including i7s, and I've just now tested the USB drive I'm trying with the Dell Pro Max and the drive works fine in other computers.  It just doesn't work on the Pro Max.
