Can't install DirectX higher than 7.0a on Windows 98 SE

[ualaa1]

Describe the bug

Direct X 8 and above gives an error saying my processor needs to be at least pentium to install even though I am emulating a pentium processor. Tried in both dynarmic_x86 and normal. The latest DirectX version I was able to install on Dosbox-X was 7.0a For testing, try to install the 08 Dec 2006 build of DirectX 9.0c from http://falconfly.3dfx.pl/directx.htm I have tested it on another emulator running Windows 98 SE and can confirm that the 2006 build is installable.

Steps to reproduce the behaviour

Does it work with cputype=pentium_mmx?

Maybe DirectX 7.0 decided to make MMX mandatory so it can do high performance blits with the MOVQ instruction.

Or, perhaps it's doing different Pentium tests than anything we're aware of.

Works fine with MMX when testing with DirecctX9.0C On ppro, it works up to directX 7.0a. DirectX 8.0 is when it begins to not allow install.

I have not tried 8.0. But I have installed 9.0c in the past without issue.
