Definition at line 83 of file abiosc.c. References USHORT. Referenced by KiInitializeAbios(). 00092 : 00093 00094 This function initializes a GDT entry for abios specific code. Base, 00095 Limit, and Type (code, data) are set according to parameters. All other 00096 fields of the entry are set to match standard system values. 00097 00098 N.B. The BIG and GRANULARITY are always set to 0. 00099 00100 Arguments: 00101 00102 GdtEntry - GDT descriptor to be filled in. 00103 00104 Base - Linear address of the first byte mapped by the selector. 00105 00106 Limit - Size of the selector in BYTE. 00107 00108 Type - Code or Data. All code selectors are marked readable, 00109 all data selectors are marked writeable. 00110 00111 Return Value: 00112 00113 Pointer to the GDT entry. 00114 00115 --*/ 00116 00117 { 00118 GdtEntry->LimitLow = (USHORT)(Limit & 0xffff); 00119 GdtEntry->BaseLow = (USHORT)(Base & 0xffff); 00120 GdtEntry->HighWord.Bytes.BaseMid = (UCHAR)((Base & 0xff0000) >> 16); 00121 GdtEntry->HighWord.Bits.Type = Type; 00122 GdtEntry->HighWord.Bits.Dpl = 0; 00123 GdtEntry->HighWord.Bits.Pres = 1; 00124 GdtEntry->HighWord.Bits.LimitHi = (Limit & 0xf0000) >> 16; 00125 GdtEntry->HighWord.Bits.Sys = 0; 00126 GdtEntry->HighWord.Bits.Reserved_0 = 0; 00127 GdtEntry->HighWord.Bits.Default_Big = 0; 00128 GdtEntry->HighWord.Bits.Granularity = 0; 00129 GdtEntry->HighWord.Bytes.BaseHi = (UCHAR)((Base & 0xff000000) >> 24); 00130 }
