请所有愿意帮忙测试安装程序的朋友运行如下命令：

footman · 发表于 2003-9-2 09:41:01

请提供：uname -m 的运行结果和 cat /proc/cpuinfo 的运行结果。
这两个命令的结果能让MagicInstaller更准确判断应该为您的系统安装什么体系结构的软件包。

谢谢。

在我机器上的运行结果如下：

Unfortunately, uname() doesn't know the difference between an i686
      // and an athlon...
      // Let's assume that anything from AMD that is i686 or higher is athlon compatible.

Configuration tools rarely have athlon entries, since athlon mostly
works for i686 "settings".  You don't want to use athlon-specific
configurations unless really necessary, as you would end up having to
support duplicate binary distributions for i686 and athlon.  Since
configuration tools may use the output of uname, you really don't
want to mess with it.

uname是不能分出i686和athlon的，
根据经验我们只能在athlon上面用i686的包，没有问题，如果用athlon的反而出错。

上面的代码跟我的想法相反:
arch == "i686" && isAMD
就作AMD处理，安装athlon的包，会不会不稳定?

大家讨论。

我的经验是我在我的 AMD XP 上安装 RH9 提供的 athlon 内核有问题，用 i686 就没问题。

也可以用model name来判定是不是athlon的cpu
不过athlon的包很少真的会失败？

cjacker · 发表于 2003-9-2 16:18:38

AMD的cpuinfo中cpu family: 6直接导致了uname()认成了i686
我觉得这应该是内核的判断问题。

是吗？难道xp和原来的版本不一样了？不就是多了一个sse?

我的duron在使用i686内核时容易死机，特别是在打开硬盘的dma时

我想vendor_id也许更合适，这样至少也可以直接说明是amd,intel.
另外要是有人用via等的cpu呢？
