| 879 | +When using a 2.6 guest Linux kernel, you should add the option | |
| 880 | +@code{clock=pit} on the kernel command line because the 2.6 Linux | |
| 881 | +kernels make very strict real time clock checks by default that QEMU | |

| 881 | 886 | If you have a slow host, using Windows 95 is better as it gives the |
| 882 | 887 | best speed. Windows 2000 is also a good choice. |

| 896 | +@subsubsection CPU usage reduction | |
| 897 | + | |
| 898 | +Windows 9x does not correctly use the CPU HLT | |
| 890 | 899 | instruction. The result is that it takes host CPU cycles even when |
| 891 | 900 | idle. You can install the utility from |
| 892 | 901 | @url{http://www.user.cityline.ru/~maxamn/amnhltm.zip} to solve this |
| 893 | 902 | problem. Note that no such tool is needed for NT, 2000 or XP. |

| 904 | +@subsubsection Windows 2000 disk full problems | |
| 905 | + | |
| 906 | +Currently (release 0.6.0) QEMU has a bug which gives a @code{disk | |
| 907 | +full} error during installation of some releases of Windows 2000. The | |
| 908 | +workaround is to stop QEMU as soon as you notice that your disk image | |
| 909 | +size is growing too fast (monitor it with @code{ls -ls}). Then | |
| 910 | +relaunch QEMU to continue the installation. If you still experience | |
| 911 | +the problem, relaunch QEMU again. | |
| 912 | + | |
| 913 | +Future QEMU releases are likely to correct this bug. | |

| 915 | +@subsubsection Windows XP security problems | |
| 916 | + | |
| 917 | +Some releases of Windows XP install correctly but give a security | |
| 918 | +error when booting: | |
| 919 | +@example | |
| 920 | +A problem is preventing Windows from accurately checking the | |
| 921 | +license for this computer. Error code: 0x800703e6. | |
| 922 | +@end example | |
| 923 | +The only known workaround is to boot in Safe mode | |
| 924 | +without networking support. | |
| 925 | + | |
| 926 | +Future QEMU releases are likely to correct this bug. | |
