Setting the Dreamcast's ISP Settings
Before your Dreamcast can dial into your computer, you need to configure it with special ISP settings. I'll walk you through how to set it up using the PlanetWeb Browser.
First boot up the Dreamcast Web Browser. When you're at the title screen, press start to get the control panel, and select 'Options'. Then select Internet Connection.
You will be presented with a three-tabbed form. The first tab is called Basic Info, and should be configured as follows:
Your Real Name - Put whatever you want here, but don't leave it blank.
User Login - Put whatever you want here, and remember it for when you're setting up the PC.
Password - Put whatever you want here, and remember it for when you're setting up the PC.
Dial Up Number - You have to put in at least one digit here.
Backup Number - Leave this blank.
DNS1 & DNS2 - Put the IPs of your domain name servers here. If you don't know them you can get them from WINIPCFG (Windows 9x) or WNTIPCFG (Windows 2000/XP). Go to the Start Menu, select Run, and type in winipcfg or (wntipcfg) and hit enter. When the dialog box comes up you should see your first DNS IP address. If you have more than one you can cycle through them by hitting the ... button.
When you have this stuff filled in, click 'OK'. The next page, Dial Options, should be set up like this:
Leave everything blank up to 'Modem Init'.
Modem Init - Use the default "AT&F0" (last digit is a zero).
Dial - Tone
Dial area code - Off
Blind Dial - On
When done, click 'OK'.
The only thing that matters on the Proxy Setting page is to click 'No' where it says 'Use Proxy'. Then click 'OK'. When you're returned to the main options screen, hit the save button to write the settings to the Dreamcast flash ROM.
