Hmm interesting I have a similar problem with a GVP SCSI card I bought. I don't have the Indy ECS yet for my 2000 but if I have the boot jumper on then I get the black screen and the power light flashes. If I take off the the boot jumper then the 2000 boots up ok. I havent solved the problem but the seller is sending me a new rom for the scsi card. If it works I will let you know.
