第三章图3.7中代码开头部分缺失注释。
原代码：
22 /* Global Descriptor Table */
23 LABEL_GDT:            Descriptor   0,                        0, 0
24 LABEL_DESC_CODE32: Descriptor      0,       (SegCode32Len - 1), (DA_C +
DA_32)
25 LABEL_DESC_VIDEO:    Descriptor    0xB8000,             0xffff, DA_DRW
26
27 .set GdtLen, (. - LABEL_GDT)    /* GDT Length */
28
29 GdtPtr: .2byte   (GdtLen - 1)   /* GDT Limit */
30          .4byte  0               /* GDT Base */
31
32 /* GDT Selector */
33 .set     SelectorCode32, (LABEL_DESC_CODE32 - LABEL_GDT)
34 .set     SelectorVideo, (LABEL_DESC_VIDEO - LABEL_GDT)
35
36 /* Program starts here.   */
37 LABEL_BEGIN:
38      mov     %cs, %ax     /* Move code segment address(CS) to data
segment  */
39      mov     %ax, %ds     /* register(DS), ES and SS. Because we have  
    */
40      mov     %ax, %es     /* embedded .data section into .code section
in   */
41      mov     %ax, %ss     /* the start(metioned in the NOTE above).    
    */

修改后应该是：
<-------------------下面的注释是为了和第41行呼应
17 /* NOTE! Wenbo-20080512: Actually here we put the normal .data section into 
18    the .code section. For application SW, it is not allowed. However, we are
18    writting an OS. That is OK. Because there is no OS to complain about
19    that behavior. :) */
