#9553: [AboutSystem] AMD Sempron is detected as Athlon 64 ----------------------------------------+---------------------------- Reporter: Kev | Owner: nobody Type: bug | Status: new Priority: normal | Milestone: R1 Component: Applications/AboutSystem | Version: R1/Development Resolution: | Keywords: Blocked By: | Blocking: Has a Patch: 0 | Platform: x86 ----------------------------------------+---------------------------- Comment (by kallisti5): calculating....

I think what is going on here is the early 64-bit Sempron cpu's were closely based on the (then new) Athlon 64 chipsets. This may be something we can't work around easily with cpuid's unless we use Axel's (kind of arbitrary) marketing name adjustments. Kev, honestly your Sempron 3100+ cpu is closer to an Athlon 64 then an Sempron :) Do you know if your cpu supports 64-bit code? -- Ticket URL: <http://dev.haiku-os.org/ticket/9553#comment:8> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
