What is the native resolution of the screen, 800x600?
If so,
	monitor=svga
	vgasize=800x600x8
are correct. You did add an ID string to /lib/vgadb, right? The
info you supplied indicated you hadn't. See the postings of earlier
today on how to get a better register dump.

Yes. No, I didn't. I am however at that point. My first question is that
I'm looking at,


0xC7345="TVGA BIOS  Z6.I1 (0.02)"		#IBM Thinkpad 760ED (U9A)
0xC7367="TVGA BIOS  Z6.I1 (0.05) "		#IBM Thinkpad 560E

so how do I pick that first ID string? Also from looking at the previous
dump it looks like I should use a match string like,

0xC????="Z6.I1"			#Should be 760/560 compatible in general
				#or is there something non-arbitrary about
				#the identifier outside of unique
				#identifier for each type of chip/card?

I was going to take the 760 listing and reduce it to the one I suggested.
I figure it can't kill anything and I can always put it back.

[9fans] Thinkpad 760XL - A question about VGA probing

[Jim Choate]

Hi,

I've got a 760XL (which is the same video hardware as a 560 which is
supported, Z6.1I - I thought anyway) that seems to work well in Linux and
Winbl^H^Hdows. I've tried 'multisync75' (default), vga, & svga no no
avail. There is a point, not shure how to describe it, where the display
jitters. I assume it's probing.

Not shure what to make of the debug, thoughts?
