Hi everyone, hi @Dietmar, I'm a retrocomputing enthusiast and I've been following this thread with great interest. I'd like to ask for some help from the community. Would anyone be able to share a complete collection of all the modified x64 acpi.sys builds released so far for Windows XP x64? I've only been able to piece together a partial version history across various threads, and I'd like to test them systematically on two machines: - ASUS F540LJ-XX028T — Intel Core i3-4005U (Haswell, 4th gen), 4GB DDR3L, Intel HD Graphics 4400 + NVIDIA GT 920M - Lenovo ThinkCentre M73 Tiny — Intel Core i7-4765T (Haswell, 4th gen) Which modified x64 acpi.sys build is currently considered best/most stable for 4th generation Intel (Haswell) hardware? I've seen references to the 5048 series, the 7777.x revisions, and some "A5x11+A5x03" variants, but I haven't found a clear recommendation specifically for Haswell. On Windows XP x86, I had good success on the same ASUS Haswell laptop with two builds: "5048 - 2019.11.1 - diderius6" and "5.1.2600.6666 - 23.10.2020". I'd like to replicate similar results on x64 now. I'm also aware from this thread that the modified intelppm.sys can cause a measurable performance drop on some CPUs (saw the report on Broadwell) — happy to benchmark this on my Haswell hardware too if that data point is useful. Thanks in advance to anyone who can help — happy to share test results/logs from both machines.
