Well, the only thing I know of to convert between HVD and LVD/SE is a multimode expander--try rancho.com for such things in this day and age. They're rare and generally more expensive than a brand new SCSI controller, though, so you probably don't want that. I wish I could help, but the only 1040B card I've got is also an HVD card. I've got a spare ISP1080, but I'm fairly certain it wouldn't work under the Miata's SRM--and I'm guessing you got the QLogic card just to have something that worked with the Miata's SRM. ;) -- Kelledin "If a server crashes in a server farm and no one pings it, does it still cost four figures to fix?"
