2.7.3 Selecting the ECP DMA Channel
The available ECP DMA channel
selections are DRQ3/DACK3 and
DRQ1/DACK1. The default is
DRQ3/DACK3. To select
DRQ1/DACK1, reset jumpers JP6 and
JP7 to 2-3.
The onboard I/O controller may either be SMC
665 or SMC 669. If you have SMC 669, JP6
and JP7 must be set to open.

forget your system password. To do
this, shut off the system power and short
pins 2-3 of JP5 for a few seconds. Reset
the jumper to normal setting by shorting
pins 1-2. Enter Setup to specify a new
password.
