Subject: 1 or 2meg users
About a week ago I posted a message to this list asking if
anyone with greater than 512k of memory was using Nitros.
I got ZERO responses. The reason I’m asking is my 2meg card.
It runs everything except Nitros later versions, I haven’t
verified 1.15 yet. The video hardware on my board is un changed
from a working proto type, which I no longer have. It appears
that GRFDRV is not allocating video memory properly. I would
LOVE to be proven wrong!
When Nitros boots, 512k or more, the first window was placed
at the top of ram, 512k. This was true even on a 2meg system. After
the boot process was complete then all additional windows would then
be allocated from the true top of RAM.
On the road for work so I’m trying to narrow this down to either
software or hardware. All I need is ONE person to say it works
on their system. :
Thanks!!

On the same topic, but using a Regular version of OS-9 6809, where
can I get the patches to GrfDrv to work properly with more than 512k?
Anyone know the bytes to patch?
Thanks,

I have NitrOS9 working on a 1Meg system. I didn’t see your earlier message,
sorry.

Could you please indicate what version of Nitros this is running on
and the ident of GRFDRV? Thanks Gene!

Yep, but in the latter versions that is taken care of in the boot process.
Thanks!
