Hi, I have an Dell "OptiPlex GX110" from Dell Computer Corporation. My BIOS Version is "Phoenix ROM BIOS PLUS Version 1.10 A05" I have windows 2000 Professional 5.0 Service Pack 3 (Build 2195) Installed in my PC. Processor -- Pentium III-E(B) SteppingB0 Motherboard -- Intel 810E PCI Chipset *** TO make a HDD "Slave" I have to REMOVE that "Jumper" or "Pin" from the Back of the HDD. Is that Correct *** I want to connect a Slave HDD, so that I can copy my stuff from my "Master" to "Slave" HDD, but I face a few problems. a.) There is no additional "Data cable" as well as "Power Cable" in my System to connect the Slave HDD. In the BIOS, I see this, Primary Drive 0 --> Hard Drive Primary Drive 1 --> OFF I'm unable to "ON" it or "Enable" the "Primary Drive 1" thru BIOS. Secondary Drive 0 --> CD-ROM Secondary Drive 1 --> OFF. In this case, Can I disconnect the CD-ROMs "Data Cable" and "Power Cable" and connect it to my "Slave HDD" without changing anything in the BIOS. i.e. to connect my Slave HDD to "Secondary Drive 0". Will this work. Are the "Data Cable" and "Power Cable" same for HDD and CD-ROM. Should i have to change anything in the BIOS before doing it. Will my "Slave HDD" be seen in the "WIndows Explorer". Is this a correct Solution or any other solutions available. Thanx in Anticipation Arsenal.
