help setup x-platform network with P4 XP Home/ eMac OSX

Medium Priority
Last Modified: 2012-05-04
I am still a bit of a novice when it comes to networking, BUT; I have decided to jump right in with both feet and try cross-platform networking as my learning model.  I have some knolwedge when it comes to computing, and built my own PC.  Networking is still a foreign subject so go easy with the abbreviations.

Could someone explain the steps nesissary in setting up my P4 2.8Ghz, A-BIT IC7-MAX3 MB, 1Ghz Twinx DDR, 160Mb (SATA) HHD, XP Home edition PC to network with an eMac Power PC G4, 256Mb, running OS X v 10.1.5?
I have a 4 meter Belkin crossover cable cat5e.

1. To share the use of a ADSL Alcatel Speed Touch Modem at 576.0 Kbps internet (USB), and a HP psc 950 (printer).
2. Use the PC as a server to run its programs ie. Autocad, Photoshop, games ect. on the Mac.
3. Keep my sanity.

Time for compleation:
2 days.

What software/ hardware, if any, do I need?

(Sorry about the lack of points for this one, but... thank you.)

Here you go...step by step.  First ink is for sharing XP to Mac OS X 10, second link is the other way around.  Should walk you through nicely.  I used them myself because Macs......*cough, cough*......sorry, can barely say the word without choking.  :)

Anyway...these should be able to pull you along very easily.





That looks good James, but-

(From the top of the link's page) "Note: The below assumes you already have both your Mac and PC computers connected to a network (ethernet or wireless) and that they can ping one another."

-how do i get them "connected to a network," and to "ping" one another?
Plug them in and assign them both IP addresses that are closely matched.  For example, you can assign the Windows XP PC an IP address of:

IP Address:
Subnet Mask:

Do the same thing on your Mac, except assign it the following:

IP Address:
Subnet Mask:

Connect your two crossover cables to the NICs of each PC, then open a command prompt on XP and try to ping the Mac.


I'm sort of a novice.
Can you explain how I, "...assign them both IP addresses...?"

1. Is assigning an IP the same on both Mac and PC's?

2. Can I pick any number for the IP addresses as long as they are closely matched?

3. Will it effect my internet connection?
What kind of Internet connection do you have?  Dial-up?  DSL?  Cable?  And do you have a router or are you directly connected to the Internet through your PC?  Mac?  It's going to make a big difference and yes, it could adversely affect your Internet connection.
There is also a how-to link on the left of that page that I gave you that shows you how to get the computers to ping each other.


I have an ADSL connection with BTopenworld.  It is in the UK.
No router, just the speedtouch modem, and I connect through the PC.

I did not see that link.  It is good.

Can you explain how I, "...assign them both IP addresses...?"

And the problems that it may cause with the internet.

You have a problem.  The ADSL modem assigns the PC its Internet address.  How were you going to connect your Macintosh to the PC without unplugging the connection to your ADSL modem?  Did you buy a second network card for the PC?  If you did, then we won't have a problem.  If not, then we could have a small problem getting this to work.  If you want to maintain your Internet connection, you will need a second NIC card or a hub.

Let me know what you've got.


The ADSL is on a USB port, and the PC/Mac connect would be through the cat5e crossover cable.  In the end though, it all goes through my onboard...

(Intel PRO/1000 CT Desktop Connection Gigabit LAN on board
Lets you easily connect to the world wide web at high speeds without having to buy a separate 10/100 Ethernet card)


Would i still need a new card?

Nope.  You're good to go.  Perform the following:

On the XP Box:

1.  Right-click My Network Places, then click Properties
2.  Right-click Local Area Connection, then click properties
3.  Highlight TCP/IP then click Properties
4.  Click "Use the following IP address" and enter the following:
  - IP Address:
  - Subnet Mask:
  - Default Gateway:  Leave blank
5.  Click the advanced button, then click the WINS tab
6.  In the NetBIOS setting box, click "Enable NetBIOS over TCP/IP"
7.  Click Ok, then OK again.
8.  Click the Advanced Tab and double-check that the firewall is disabled (no check in the box).
9.  Click OK and you're done setting up and address on the XP box.

For the Macintosh...visit the following link:


Use IP address:
Use Subnet Mask:

Leave all other fields blank.

You should be able to ping each other now.

I will try that, and thank you.

One more.
 Will i just access the internet on the mac through the pc's connection software, or will it connect with its own software through the pc?
Well, that might be difficult.  I'm not sure how your would do it, to be honest.  If you intend to access the Internet, then you need to set the default gateway of the NIC on your XP machine to match your DSL modem's address.  Then you would need to set the default gateway of the MAC to be the NIC of the XP machine.  It'll get more complicated.  That may not work...and you may also have to set the DNS address on the XP NIC card to match that of the ISP (the one on the modem).
