## 7.4.2 CTC CHANNEL ZERO DEFAULT OPERATING MODE

Traditionally, CTC channel zero has been set to operate in mode three by the
BIOS POST, but recent 486 BIOSes that I have seen appear to be using mode two
by default. The only significant differences are the width of the pulse from
the CTC pin that triggers the timer tick interrupt, which is narrow in mode
two but is still plenty wide enough for the Intel 8259 PIC chip, and the value
read from the CTC channel zero counter (which decrements twice as quickly in
mode 3).
