Mac Rom

[阿扁]

我想問一下那個Mac Rom 的東西有什麼用?

[CD]

請問您在那裡發現Mac Rom的呢？或......您指的Mac Rom是那一個呢？

CD兄
我指的是 OS 9 上的，有什麼用。
os x 上是否沒有 MAC ROM 了。

扁兄指的是以上的 ROM ...

在此小弟只能給 brief description in English ... 抱歉 ...

<BLOCKQUOTE><font size="1" face="XYZ">quote:</font><HR>The System file and the ROM work together to create an operating system. The System either adds to or replaces parts of the ROM. Apple, for example, improves or enhances its system software at least twice a year and sometimes more often than that. (Think Mac OS 9, Mac OS 9.0.4, Mac OS 9.1, and so on.) When the ROM of every Mac took the form of permanently etched silicon chips, this was a clever system; you can imagine what a mess you'd have if Apple had to replace your Mac's ROM chips twice each year! Instead, the company could just create a new software-only System Folder with programming that supersedes or adds onto what's in ROM.

Now that the ROM is mostly in a file in your System Folder, the ROM file can be updated more easily - but the precedent has already been set. You need both files for a functioning Mac.<HR></BLOCKQUOTE>

Think the latest ROM version is 9.3.x

那我在os x上看到的boot rom是不是和ibm-pc的BIOS
相同。還是有其他的作用。
