Hello Karsten, thanks for the information - that explains why my emulated pentium failed already at 0x...6bb because not supporting sse at all.
>From wikipedia [1] the pminud instruction at 0x...6fb got introduced with sse4.1 which seem not supported from your flags line (while on the other side intel says [2] it is a Penryn). (Might there be a bios switch?) Kind regards, Bernhard [1] https://en.wikipedia.org/wiki/SSE4 [2] https://ark.intel.com/content/www/de/de/ark/products/37253/intel-pentium-processor-t4300-1m-cache-2-10-ghz-800-mhz-fsb.html
