In message <[EMAIL PROTECTED]>, Derek Stewart <[EMAIL PROTECTED]> writes HI, There is no benfit of using 80 wire IDE cables, as the IDE controller can not take advantage of the higher speeds like on PCs... I was commenting in general. The Q.xx controller is ATA 66 isn't it ? I don't recall seeing any other ones on IDE I have build many PCs, and it does not matter where to the CDROM is or device on the IDE cable. Unless it using 80 wire conductors or uses cable select. I have had problems with some - Plextor CD-RWs usually. I was very puzzled the first time it happened when I built a machine for someone who wanted to use the DVD writer out of his old machine. I set the Plextor up as a slave and stuck it on the middle connector so I could just put the DVD-ROM drive in - damn thing would not even see the drive to let me install any software until I moved it. -- Roy Wood Q Branch. 20 Locks Hill, Portslade, Sussex.

It may well work, but there will be signal degradation. -- QBBS (QL fido BBS 2:252/67) +44(0)1442-828255 tony@.co.uk http://www.firshman.co.uk Voice: +44(0)1442-828254 Fax: +44(0)1442-828255 TF Services, 29 Longfield Road, TRING, Herts, HP23 4DG
