Title: connecting a harddrive to a mobo
Post by: Sean on July 24, 2004, 08:16:29 PM

If it says something such as 2x UltraDMA 100, 1x UltraDMA 133(from Promise 20378) up to 6 Devices does that mean i have to connect a Hard Drive with a UltraDMA interface or can i use a EIDE or SCSI or Serial ATA.  But i cant find a hard drive with UltraDMA interface.

The 'Ultra DMA' interface is capable of connecting to EIDE drives with an 80-line cable. The Promise card is capable of supporting three cables, and of co-existing with the mainboard adaptor. You can also use the ATAPI adaptor on your MB, for another two (or more, on some MBs) cables. Each cable supports 2 drives.

Connect the newer 'high speed' drives to the UDMA, 'Ultra', or EIDE ports with 80 line cables. Connect CDROMs, older HDs (UDMA 0, 1, or 2 and PIO-only), and cartridge drives (IDE ZIP, JAZ, Orb, SyQuest, and 3M LS) to the non-ultra channels (or to backward-compatible extra ultra channels) with 40-line cables. Connect DVD drives to either Ultra channels with 80 line cables or to non-Ultra with 40 line cables.
