I was unable to find a web page at Gateway describing the exact model,
but the BIOS shows 4L3TT0X0.15A.0010.P13 as a BIOS version,
and I eventually found references to the motherboard at
http://www.gateway.com/support/techdocs/references/motherboard/4l3tt0x0/4l3tt0x02.shtml
and

The machine is a 233 MHz Pentium 586 with 192MB of main memory and has a 4GB Caviar hard drive. It has a Gateway EV700 monitor. The machine came to me with Windows NT installed, but I wanted to test some Windows 98 software. Since there is no upgrade path from NT back to 98, I was forced to reformat the hard disk, and installed Windows 98 and Debian. Even though there are 8912 cylinders on the hard drive, the "cylinder 1023" problem never appeared, perhaps because LBA addressing is enabled on the drive.
The Gateway EV700 horizontal sync range is 30-69 Hz and
vertical sync range is 50-120 so
this modeline
"1280x1024" 110 1280 1328 1512 1712 1024 1025 1028 1054
works fine for 8 bit depth using the Mach64 server.
Somebody gave me a Microsoft scrolling mouse but I have had some problems getting it setup and I am thinking of junking it and using a 3-button Today's Mouse which also works fine with the Fujitsu. Here is the XF86Config file. (document changes from default setup).
Here are my raw notes on the installation. Watch this space for progress...
