I got the following message:

Unexpected interrupt or trap: vector = 13.  pc = 0x147  text+data+bss = 0x11E

My Norton Programmer's Guide tells me that interrupt 13 (decimal) is invoked
during the vertical retrace period on a color display.  I am using an ATI
VGAWonder 512k VGA card.  It seems to work OK, but I have gotten this error
twice.  Paul Allen tells me that the kernel ought to charge right on after it
gets this error, but it doesn't -- it hangs.  Completely.

I am wondering if anyone else:

	1)  Has this problem.
	2)  Has an ATI VGAWonder (256 or 512k)
	3)  Knows what I can do about it.

Please email me with responses (b-cox2@uiuc.edu) and I'll post a summary of the
responses.
