30;--------------------------------------------------------------------
31; Prints Hard Disk configuration for drive handled by our BIOS.
32; Cursor is set to configuration header string position.

34; BootMenuPrintCfg_ForOurDrive
35; Parameters:
36; DS:DI: Pointer to DPT
37; Returns:
38; Nothing
39; Corrupts registers:
40; AX, BX, CX, DX
41;--------------------------------------------------------------------
42.BootMenuPrintCfg_ForOurDrive:
43 eMOVZX ax, [di+DPT.bIdevarsOffset]
44 xchg bx, ax ; CS:BX now points to IDEVARS
[421]45 ; Fall to .PushAddressingMode
[392]46
47;--------------------------------------------------------------------
[421]48; .PushAddressingMode
[392]49; Parameters:
50; DS:DI: Ptr to DPT
51; CS:BX: Ptr to IDEVARS
52; Returns:
53; Nothing (jumps to next push below)
54; Corrupts registers:
[421]55; AX, CX, DX
[392]56;--------------------------------------------------------------------
57.PushAddressingMode:
[422]58 ACCESSDPT__GET_UNSHIFTED_TRANSLATE_MODE_TO_AXZF
[392]59 ;;
60 ;; This multiply both shifts the addressing mode bits down to low order bits, and
61 ;; at the same time multiplies by the size of the string displacement. The result is in AH,
62 ;; with AL clear, and so we exchange AL and AH after the multiply for the final result.
63 ;;
[422]64 mov cx, g_szAddressingModes_Displacement << (8-TRANSLATEMODE_FIELD_POSITION)
[421]65 mul cx
66 xchg al, ah ; AL = always zero after above multiplication
67 add ax, g_szAddressingModes
[392]68 push ax
[421]69 ; Fall to .PushBlockMode
[392]70
71;--------------------------------------------------------------------
[421]72; .PushBlockMode
[392]73; Parameters:
74; DS:DI: Ptr to DPT
75; CS:BX: Ptr to IDEVARS
76; Returns:
77; Nothing (falls to next push below)
78; Corrupts registers:
79; AX
80;--------------------------------------------------------------------
81.PushBlockMode:

89;--------------------------------------------------------------------
90; PushBusType
91; Parameters:
92; DS:DI: Ptr to DPT
93; CS:BX: Ptr to IDEVARS
94; Returns:
95; Nothing (jumps to next push below)
96; Corrupts registers:
97; AX, DX
98;--------------------------------------------------------------------
99.PushBusType:
100 mov al,g_szBusTypeValues_Displacement
101 mul BYTE [cs:bx+IDEVARS.bDevice]
102
103 shr ax,1 ; divide by 2 since IDEVARS.bDevice is multiplied by 2
104
105 add ax,g_szBusTypeValues
106 push ax
107
108;--------------------------------------------------------------------
109; PushIRQ
110; Parameters:
111; DS:DI: Ptr to DPT
112; CS:BX: Ptr to IDEVARS
113; Returns:
