Do you mean PCG-F590? F690 does not seem to exist on www.sony.com.
What exactly are the ATI chipsets? The newer VAIO laptops
all use Neomagic 256XL+ for their video chips. (unless I am wrong)
On Mon, Nov 06, 2000 at 09:29:26AM +0800, Peter Wemm scribbled:
| The problem comes from having an 80K video bios (0xc0000 -> 0xd3ffff).
| This breaks two things:
|
| 1: the default pccard (oldcard) address is 0xd0000 and overlaps with the
| rom, which causes pccardd to see garbage instead of the CIS>
Ah, this explains why I cannot get oldcard to work. However, have
you gotten oldcard or newcard to work with another memory address?
If so, what iomem did you use?
| 2: XFree86 carefully calculates the size of the ROM, and then memcpy's
| all 80K of it onto a 64K stack buffer. Sigh.
Does this patch just fix the video support? or does it also
resolve the pccard problem? I will test it tonight.

| 3: NEWCARD doesn't seem to have any way to change the CIS window address.

Right, same problem here with VAIO Z505JS.
| After getting over the initial hurdles, I'm pretty happy with it. It isn't

Bah, Let JHB keep his 1600x1200 15in screen. :-)
