Hi Cal,

I don't know whether in the interim your problem has been solved, but I 
have had no problems whatsoever here with a DIAMOND NVidia RIVA TNT2 
32MB AGP card with my Trinitron CRTs or 17" Flat-Panels. I am using a 
reasonably recent version [Build 478] of SNAPse, so I'd suggest you 
update your circa 5-year old SDD drivers to currently available SNAP 
driver on ecomstation.com!

I presume that you didn't actually want to run as only 640 x 480 as 
defined in your config.sys above?

These are my lines from current config.sys:

    SET DISPLAYTYPE=VGA
    SET VCFG_NO_DDC=TRUE
    DEVINFO=SCR,VGA,E:\OS2\BOOT\VIOTBL.DCP
    SET VIDEO_DEVICES=VIO_SVGA
    SET VIO_SVGA=DEVICE(BVHVGA,BVHSVGA)
    DEVICE=E:\OS2\MDOS\VSVGA.SYS
    SET GRADD_CHAINS=C1
    DEVICE=E:\OS2\GRADD.SYS
    DEVICE=E:\OS2\MDOS\VMANWIN.SYS
    SET GREEXT=SDDGREXT
    SET C1=SDDGRADD
    DEVICE=E:\OS2\SDDHELP.SYS

I don't think an SDD from that vintage had an \os2\drivers\nucleus 
directory tree, but for quite a while SNAPse has had an 
\os2\drivers\SNAP tree which replaced it, but it has to be manually 
removed - if running SDD you don't need to reset the system back to VGA 
to update to SNAP, just run "SETUP SNAP" from the directory you expanded 
the SNAP installation executable into [by running
" -d"]

HTH

Regards,
Mike
