So, many people using OSx86 are using netkas’s fake EFIimplementation called PC_EFI, but not many people know that a better,more open fake EFI implementation has emerged. Chameleon, led by zef,Kabyl, and other developers aims to create an open-sourceimplementation for OSx86 users. So its open, is that it? No, Chameleonposes many advantages over traditional PC_EFI and here is a quote ofthe list of advantages from zef, the lead developer:

* Provides the same (fake) EFI features as PC_EFI
*device-properties string in the com.apple.Boot.plist can haveline-breaks, tabs, spaces. With PC_EFI you must keep the whole stringin one single line - which is hard to maintain.
* Unifiedboot0/boot1h for MBR/GUID partitioned disks - PC_EFI uses a separateboot0/boot1h for GUID disks which makes DVD builders and users workharder.
* boot0 can even pick-up unactivated primary HFS+ partitions - PC_EFI can’t.
*cdboot is also available (works now with JMicron connected IDE DVDdrives) - you can’t get cdboot with PC_EFI. DVD builders would be happywith that, it makes their - and our - life easy.
* Can boot from software RAID configs - PC_EFI can’t.
*Don’t need to hassle with startupfiletool anymore to embed the stage2boot onto your partition, instead just copy the ‘boot’ file to yourroot folder as a single file. boot1h is still compatibile with the oldstartupfile loading method.
* Installation takes only 3 steps:
Suppose that your installation is on /dev/disk0s2
1. Install boot0 to the MBR: fdisk -f boot0 -u -y /dev/rdisk0
2. Install boot1h to the partition’s bootsector: dd if=boot1h of=/dev/rdisk0s2 bs=512 count=2
3. Install boot to the partition’s root directory: cp boot /
* Supports more CPUs (AMD, Intel SSE2) - PC_EFI only supports Intel CPUs.
*As a bonus we’re providing a Vista friendly fdisk which won’t breakyour current Vista installation in case of dual-booting scenarios.
* Chameleon is an opensource (APSL) and open-minded project - how about PC_EFI?

As you can see, Chameleon has many advantages, and chances are, ifyour computer works fine with PC_EFI then it will work well, or evenbetter, with Chameleon. I have switched all my OSx86 installs over toChameleon and I can say that its working amazingly with no problemswhatsoever. The official site of Chameleon is at:
http://chameleon [DOT] osx86 [DOT] hu
You can find information, downloads, and updates there. JaS alsocomments that he will be using Chameleon rather than PC_EFI in his next10.5.3 OSx86 release.

wow, it seems good

jas的10。5。3的版本出不来了吧，这都10。5。4了

Chameleon出的boot偶已經在使了.....相當的不錯...建議大家試試

我已經上傳

where?

不知道这东东能否解决我双核的问题

貌似那人已经解决jmicro ide问题了...nb

看看看啊

eh  能告诉我有什么改进么?

* Supports more CPUs (AMD, Intel SSE2) - PC_EFI only supports Intel CPUs.

!!!怎么个意思?!SSE2?!

这里下载，MS要刻盘：

这东西我曾经测试过，会导致我的8800gt启动后黑屏，就没深入研究，如果不是使用guid的分区，建议还是用efi v8吧

针对几个黑金塔版本都出了相应的ppf补丁，还有独立安装的也有

好像是指 让amdsse2用上原版内核?

貌似不是讓amdsse2用上原版內核...而是正確識別前端總線程........不過我試了一下在PD820上沒用.明明是800Mhz的總線程確識別為3.2Ghz....暈了

That's Cool!
I'll try it!

Chameleon----变色龙 http://chameleon.osx86.hu
Netkas----PC_EFI

都有EFI欺骗功能，（fake EFI）

1.device-properties string 更灵活 （支持换行、tab、空格）
2.不管是MBR还是GUID的分区，使用统一的 boot0/boot1h，而PC_EFI针对MBR和GUID则有着分别对应的代码，这使得DVD的制作和用户的使用变得麻烦。（太酷了！）
3.boot0甚至可以引导未激活的HFS+主分区，而PC_EFI做不到。
4.cdboot也已经可用，完美工作与连接在JMicron芯片上的IDE DVD。而PC_EFI没有???（原文：you can’t get cdboot with PC_EFI.）(不对吧？那我们之前用的这些破解的DVD的boot代码都是谁的？) DVD的制作者将会happy，它使我们 life easy!(的确！这是实话！)
5.支持操作系统级别的Soft RAID，PC_EFI不行。
6.不再需要用startupfiletool来将stage2的boot嵌入你的分区（即论坛里所谓的“可见的第二引导”）；取而代之的仅仅是将 ‘boot’这个文件copy 到你要引导的分区的根目录；且boot1h将仍然兼容startupfile的loading的方法。

安装步骤不需要翻了吧！
* Installation takes only 3 steps:
Suppose that your installation is on /dev/disk0s2
1. Install boot0 to the MBR:
fdisk -f boot0 -u -y /dev/rdisk0
2. Install boot1h to the partition’s bootsector:
dd if=boot1h of=/dev/rdisk0s2 bs=512 count=2
3. Install boot to the partition’s root directory:
cp boot /
以下是作者 PS:
*支持更多的CPU（AMD、Intel SSE2）PC_EFI只支持Intel CPU.(不对吧？)
*作为一个红包，我们提供一个Vista友好的fdisk程序，它使得在双引导的方安里，不会损坏你当前安装的Vista.
*变色龙是一个开源的(APSL)和open-minded project，而PC_EFI呢？
