RE: Connecting harddisk
Yes, it can be done but lp0 and lp1 is not enough. Serial port
2 and 3 are also multiplexed with SCSI and IDE. For IDE port 0
and 1 some of the pins are located on serial port 2. For IDE
port 2 and 3 some of the pins are located on serial port 3.
The pins you need on serial 2 and 3 are available on pin headers
before the serial transceivers.
The PCB is prepared for circumvention of the buffer on lp 0
(there are pads for resistors under the buffer).
Another option is to use an Axis StorPoint NAS 100/IDE hardware
and run elinux on that. This hardware requires no patching to
be used with elinux and IDE drives.

Subject: Connecting harddisk
I'd like to know if it is possible to connect a standard ide harddisk to the
devboard using the lp0 and lp1 pins available. If I'm not completely wrong,
the same pins on the etrax are used for both scsi, ide and parallell ports.
Also, there is the issue of buffered ports on lp0 - can one circumvent the
buffering, or am I limited to using lp1 pins only?
Thanks in advance,
