Hi All - update from my '2nd Hard Drive' thread................. here's the outcome.
I purchased a SATA to IDE converter as per Mark's recommendation.
Leaving my set-up as was - IDE cable from mobo to 1st hdd (sda), then to 2nd hdd - (sdb), I connected the new set up from SATA on mobo to optical drive. Boot failed and sat at the options screen (post, bios, boot etc.) Hitting DEL to access bios had no effect.
I then swapped the SATA converter to sdb and IDE cable to sda and optical drive. Same - no boot.
I then connected SATA converter to sda and IDE cable to sdb and optical drive - bingo! Boot achieved as normal, BUT - system doesn't 'see' sdb or optical drive! So no further on............
I suspect this is a motherboard issue as it seems that when a SATA connection is made it 'ignores' the IDE one. Changing various settings in bios re: SATA/IDE controllers has had no effect. Anyone shed any light?
Thanks as always
