Hi All!
I just notice that in the Windows 10 Build 19041 (version 2004) I see no HAL symbols. Instead of symbols just a strange output (see below). Kernel symbols are displayed OK and, of course, I'm using BIOS and not UEFI version.
I'm interested, if anyone else have the same problem and, generally, if Microsoft changed policy about symbols.
Thank you in advance,
Al

I don't know what those symbols are but HAL is now included in the NTOS image:

Hi Scott,
Thank you very much for the information. I found it. Do you know the reason? Is Microsoft explain this change somehow?
I do not know the definitive reason. However, ever since Vista there has only been one HAL per-architecture so having separate Kernel and HAL images is unnecessary.

Thank you very much Scott. I appreciate your input.
With best regards,
