Internet Sharing, CD Backup, and Video Ports December 28th, 2001
Greetings, folks. Well, I just couldn't let the new year go by without writing one last column for 2001! And boy, is this a good'un! Today we talk about sharing an Internet connection between Macs and PCs (both wired and wirelessly!), connecting an old Mac to a new monitor, and backing up your install CD's. If you have a question of your own, you can e-mail me, or ask in the Ask Dave/Mac Support Boards, where everyone can take a stab answering your questions! For now, read on!
Tom Coscarelli writes, "I have two Dell computers, with Windows ME. I have a cable modem connected to one computer and have a wireless peer-to-peer network connecting them to each other via PCMCIA cards. My son has a new iMac and I wonder if there is a way to get his computer linked to the wireless PC connection - for the Internet."
You're likely in luck here, Tom. The Internet Connection Sharing in Windows typically uses standard DHCP, and the "ad hoc" networks created by Windows-based 802.11b wireless cards are the same as "computer-to-computer" networks on Macs. So in theory what you would need to do is:
Install the AirPort card and software in your iMac
Set AirPort to connect to your existing "computer-to-computer" network
Set TCP/IP to use AirPort and DHCP
Fire up your web browser and enjoy!
Let us know if you have any problems, and we'll try and get them ironed out!
Sherry Svec writes, "We installed a DSL modem with a d-link router yesterday. The two PCs are fine with it but the iMac doesn't seem to understand that DSL exists. It's a blueberry iMac operating on Mac OS 9. We have an Ethernet cable attached but can't seem to progress any further. Can you help?"
Without knowing more about your setup, it's tough to say for certain, but I'll make some assumptions and take some guesses and, hopefully, guide you down the right path. My guess is that your d-link router is configured to share one IP address and assign (via DHCP) "dummy" IP addresses to all the computers in your house. I would also wager that your Windows machines are configured to "Obtain an IP Address Automatically" and that it is working properly. Lastly, I would assume that you're getting a "link light" on the Ethernet port to which you're connecting the iMac. Given these assumptions, your solution is similar to that of Tom above.
Open up your TCP/IP Control Panel
Set "Ethernet" and "DHCP" here.
Close the Control Panel, and agree to save the changes.
Open up your web browser and you should be online.
If this doesn't do it for you, then there's likely something not configured properly within the router, or perhaps you have a bad Ethernet cable going to the iMac.
David Knopfler writes, "I have a 19" PC monitor which has a cable ending in 14 prongs laid out in three rows - 5 / 3 +1 /5 - I want an adaptor that will convert this to a standard Mac cable so I can connect this monitor to a Mac 7300 computer. What do I need to purchase?"
David -- It sounds like you have a typical SVGA monitor. Most (if not all) "newer" Macs will support this, but some older ones (like your 7300) still used the Mac-specific, "2-row" connector. Griffin Technologies sells an adaptor that will suit your needs (their website is currently being revamped, so I can't give you a specific product number, but call them at 913.381.5545 and they'll get you what you need).
Lazy Boy writes, "Having trawled the net I still cannot find an answer to my question which is 'what is the best way to backup my OSX10.0.3 and 10.1 Install CD's' - I need to do this desperately since I'm shortly due to go on travels and don't particularly want to take the originals - HELP !!!!! Thanks."
Well, Lazy Boy (hey, he said it first!), the best way is to use your CD burner and copy the CD with that. Apple's Disk Copy or Roxio's Toast will make this process pretty easy for you, and that's your safest bet. I'm no lawyer, but my guess is that "fair use" applies here, and making a backup copy for yourself (and only yourself) is probably OK. If you don't have a CD burner, then you can make disk images with Apple's Disk Copy and store them on your hard drive or some such. You can't boot from them, but at least you've got something in the event that your CD gets destroyed. You then would have to obtain a burner and make yourself a new copy from which you could boot.
Or, if you're really lazy, you could just buy another copy of 10.1. :-)
That's it for this year, folks! If you have any comments about the items discussed here, please post them in the comments below. If you have a question of your own, please feel free to send it to me at email@example.com, or ask in the Ask Dave/Mac Support Boards. I'll see you next year!
PS. Have a Nice Day.
