Hello, I cannot get my HP Pavilion ZE4200 into EPP mode. The bios will not allow port settings, and I cannot seem to do it from windows xp home. Anyone else had this problem? I am assuming will NOT work from ECP mode as I have been told. I just got my olimex dev boards in. Thanks Glen

I just got my olimex dev boards in. It should work in any mode other than ECP, if that helps. Leon

Glen, Actually, not a bad shot. I have some VB code that uses a driver in Windows XP to change the port from SPP to EPP. The basis for the command string is "Parallel Port Complete by Jan Axelson. I have lost your email address, contact me off list and I'll send you the code. It's only a very few lines. You could just write a small utility that made the change. I don't know how to change it back but that shouldn't be difficult to figure out.

Richard, I need to go from ECP to EPP. I am wondering if my laptop's motherboard even supports EPP at all. Thanks, Glen rtstofer wrote:

Guys, I think HP should have utility to do this for you. Go to HP's web and look for such utility /patch..

Richard,
I need to go from ECP to EPP. I am wondering if my laptop's
motherboard even supports EPP at all.
Thanks,
Glen

Most motherboards, laptops included, use a Super I/O chip of one
sort or another. These chips combine serial, parallel, floppy and
sometime IDE all in one package. I don't KNOW that your laptop will
respond to the code but I do know that if the port doesn't show up
at 0x378 (as an ISA port) there is no hope. Strictly PCI ports
can't be manipulated with the driver/setup code I use.
And, I had a heck of a time finding another ISA card for my desktop.
I would think you could look in Device Manager and find out what
address the parallel port uses. By default, mine uses 0x378 in ECP
mode. I change it to EPP when I run the logic analyzer and I don't
think I change it back. I don't have an attached printer,
everything is networked.
The code is trivial:
Public Sub PortSetup(ByVal PortBaseAddress As Integer)
SPPDataPort = PortBaseAddress
StatusPort = PortBaseAddress + 1
ControlPort = PortBaseAddress + 2
EPPAddressPort = PortBaseAddress + 3
EPPDataPort = PortBaseAddress + 4
ECPConfigPort = PortBaseAddress + &H402
ECPEIR = PortBaseAddress + &H403
ECPControl2 = PortBaseAddress + &H404
Out(ECPConfigPort, &H94)
Out(ECPEIR, &H2)
Out(ECPControl2, &H10)
Out(ControlPort, &HC4)
End Sub
but it relies on a driver named 'inpout32.dll' declared as:
Public Declare Function Inp Lib "inpout32.dll" Alias "Inp32" _
(ByVal PortAddress As Integer) _
As Integer
Public Declare Sub Out Lib "inpout32.dll" Alias "Out32" _
(ByVal PortAddress As Integer, _
ByVal Value As Integer)
The driver is available here: http://www.lvr.com/parport.htm Look
about 2/3 the way down the page.
Your mileage may be all over the map...

>>I need to go from ECP to EPP. I am wondering if my laptop's >>motherboard even supports EPP at all. >> Hi Glen, I haven't been following the whole thread, but what options does your BIOS give? If you want to learn lots about the parallel port, take a look at Craig Peacocks web site (there's lots of other interesting h/w stuff there too): http://www.beyondlogic.org If you have a Linux system, or can use a Linux boot CD, you try the Linux parallel port user-space driver (ppdev). Tim Waugh wrote the driver, and there is a PDF document describing it in various places around the web. The user-space driver has a negotiation phase where you can ask it to select the parallel port mode. You can see if that can get you into ECP mode. Watch-out for this though: On the HP Omnibook 6100 the parallel port is also used for the floppy drive. It uses a Super I/O chip that can multiplex a parallel port or floppy drive on the DB25. The mode pin of the chipset is driven in an 'application specific' (i.e., HP defined) way to determine when a floppy is connected. It turns out that the Cypress CPLD JTAG programming cable matches that definition, so promptly crashes windows when you plug the cable in - since it fails to find a floppy drive attached. Of course to figure this out, I used Linux :) Cheers Dave
