NPU functions are not correct: NPU Trigonometric Functions: FAILED. Seems to be a problem of the instruction set. 2.) Real-Time Clock Alarm: FAILED (This might be also the reason for the KVM problem, see my previous post). Seems to be that real-time clock is not working correct. 3.) There is also a problem with the reported base memory under QEMM386 (HIMEM.SYS and EMM386.EXE is correct here). It is 646kB instead of 640kB. Therefore base memory test fails. I guess that reporting memory CMOS tables/interrupt functions are not implemented correctly. Details are listed below. All issues are NOT present under VMWare Server 2.0 and with real hardware. QEMU: 0.12.3 under Fedora 11, 2.6.30.10-105.2.23.fc11.x86 on AMD Phenom II Quad Core, x86_64-softmmu. Any comments? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/ Details: 1.)
