Both 4.1 and 4.2 works on A7V in my experience. There is a random hanging time during probing the ATA66/100 dirves. I just found some interesting issue for ATA-66/100 drives to cause such hang. I bought a bounch of ATA-66/100 WDC and Maxtor drives (10/20/40/45/60/80). Even with the same type of drives, say WDC450AA, each dirve has different response time the Tx rate (slightly different). If putting them on the same IDE bus, they cause trouble for the Tx rate. I do not have any detailed information on why this happens because I do not have time to analyse the singnal on the IDE bus. I guess there is confilct on the bus. About 8 years ago, when seagate Elite-2 came to the market, this dirve always try to grab at least two bus cycle before releasing the bus. It caused numbers of bus reset and reduced Tx rate to the half if more than one drives on the bus :-( (that was SCSI bus) I am not familiar with IDE signal. But I guess there is similar thing happened to these new drives that may not complaint with ATA-66/100 standard. Try to use one ATA-100 drive on each IDE bus to see if that work for you. -Jin On Mon, 11 Dec 2000, Drew Sanford wrote: > This didn't require any magic on my part - once I got my NIC and > parralel port to stop fighting over the same IRQ.
