Hi all. Posting this for a friend who owns an HP Pavillion 7955. He recently fried his H/D and replaced it with a 40gig Maxtor making sure the jumper was set as master and had the proper 80 pin shielded cable. The problem is that even though the bios picks it up as ultra dma 5, checking in hardware/system properties shows it up as being PIO. The option to use DMA if available is enabled. His previous drive was a Seagate 40 gig. We downloaded the latest inf files from Intel etc ... but to no avail. Any suggestions ?
