Driver Flags
bit 8 NOCHECKSYNC
The psm driver tries to detect the first byte of the data
packet
by checking the bit pattern of that byte. Although this method
should work with most PS/2 pointing devices, it may
interfere with
some devices which are not so compatible with known
devices. If
you think your pointing device is not functioning as
expected, and
the kernel frequently prints the following message to the
console,
psmintr: out of sync (xxxx != yyyy).
set this flag to disable synchronization check and see if it
helps.
to set this flag recompile a kernel with "flags 0x100" added to the end
of the psm line.
device psm0 at atkbdc? irq 12 flags 0x100
