I don't know what card you are actually working, I am using a Trident 1Mb VGA card. Puting the DIP switch 5 to on solved my problem. I would advice you to check that your jumpers on the number of DRAM chips you have must be set correctly. Switch 5 changes from fast address decode (off - default) to slow address decode (on - must for SCSI,RLL and some others). You may have to change a jumper (can't remember which) which says that it uses standard bus and not autodetect bus. Well, I hope this helps. Michael
