1387 + 1024) would then be available for use exclusively by the driver.

65 * Watchdog Timer Configuration
66 *
67 * The function of the watchdog timer is to reset the system automatically
68 * and is defined at I/O port 0120H and 0121H. To enable the watchdog timer
69 * and allow the system to reset, write appropriate values from the table
70 * below to I/O port 0120H and 0121H. To disable the timer, write a zero
71 * value to I/O port 0121H for the system to stop the watchdog function.
72 *
73 * The following describes how the timer should be programmed (according to
74 * the vendor documentation)
75 *
76 * Enabling Watchdog:
77 * MOV AX,000AH (enable, phase I)
78 * MOV DX,0120H
79 * OUT DX,AX
80 * MOV AX,000BH (enable, phase II)
81 * MOV DX,0120H
82 * OUT DX,AX
83 * MOV AX,000nH (set multiplier n, from 1-4)
84 * MOV DX,0120H
85 * OUT DX,AX
86 * MOV AX,000mH (set base timer m, from 0-F)
87 * MOV DX,0121H
88 * OUT DX,AX
89 *
90 * Reset timer:
91 * MOV AX,000mH (same as set base timer, above)
92 * MOV DX,0121H
93 * OUT DX,AX
94 *
95 * Disabling Watchdog:
96 * MOV AX,0000H (a zero value)
97 * MOV DX,0120H
98 * OUT DX,AX
99 *
100 * Watchdog timeout configuration values:
101 * N
102 * M | 1 2 3 4
103 * --|----------------------------------
104 * 0 | 0.5s 5s 50s 100s
105 * 1 | 1s 10s 100s 200s
106 * 2 | 1.5s 15s 150s 300s
107 * 3 | 2s 20s 200s 400s
108 * 4 | 2.5s 25s 250s 500s
109 * 5 | 3s 30s 300s 600s
110 * 6 | 3.5s 35s 350s 700s
111 * 7 | 4s 40s 400s 800s
112 * 8 | 4.5s 45s 450s 900s
113 * 9 | 5s 50s 500s 1000s
114 * A | 5.5s 55s 550s 1100s
115 * B | 6s 60s 600s 1200s
116 * C | 6.5s 65s 650s 1300s
117 * D | 7s 70s 700s 1400s
118 * E | 7.5s 75s 750s 1500s
119 * F | 8s 80s 800s 1600s
120 *
121 * Another way to say the same things is:
122 * For N=1, Timeout = (M+1) * 0.5s
123 * For N=2, Timeout = (M+1) * 5s
124 * For N=3, Timeout = (M+1) * 50s
125 * For N=4, Timeout = (M+1) * 100s
