Adding 1M more to W32i? Worth it?

Adding 1M more to W32i? Worth it?

Post by Pui Yin James S » Fri, 30 Jun 1995 04:00:00



I have 2the Max Tseng Lab W32i rev.b. (1M)

I would like to know what I could get if I add 1M more RAM to it.

I guess that: 2M => 1024x768 (65k color)
                 => 1280x1024 (256 color)
                 => 800x600 (24-bit color)?!

Anythin else? Faster?

BTW, I could only get 60Hz max. refresh rate at 640x480 (24-bit color),
and at 800x600 (16-bit color). Could anyone tell me if I can use 72Hz for
these modes? I did try "vmode 640-72" and "vmode 800-72" but it didn't
help. It works only for 256 color modes :-(

Please drop me a few lines.

Thanks in advance. :-)

I think it shouldn't be worth it since there's something in the docs that
said that only 8bpp (256 colors) was supported. But,

You got more than 256 colors? How did you do this? (I use the XF_W32 [or
something like that] server.)

The refresh rate is going to depend on the board's DAC and you monitor.
I know on my Hercules ET4000/w32i it will do at least 72Hz at 24bit in 640x480.
The ET4000/w32i and p are supposed to interleave DRAM in Windows so for
modes using 1MB adding the extra 1MB is supposed to use both banks to
increase Windows performance.  You can only get 24bit in 640x480 on the
w32i the w32p gets 800x600 24bit.
