My experience with changout of my old 1x Matshita UJ-810 with the NEC ND-6500a.
My Toshiba 5205-S705 laptop had the UJ-810 installed as a slave. The new ND-6500 came as cable select and caused an IDE error#0 when installed. After reading various forum posts on this issue I learned about â€˜reverse ATAâ€™. I ordered a â€˜Slimline to IDEâ€™ adapter. Using this adapter, I installed the 6500 in my desk top PC on the secondary IDE cable. It was recognized as master and slave depending which connector I hook it up to. Following the instructions fromâ€™6500bootâ€™ I created a bootable CD with Nero and added all the 6500boot programs. I booted to DOS, but when I tried to run the 6500 boot program, I got a message saying â€˜firmware not changed correctly, 6500boot.bat missing.â€™ After trying MANY different combinations and 2 PCs, I made a bootable floppy with all the BOOT6500 programs. Restarted PC and booted to DOS from the floppy. Ran BOOT6500.bat successfully! After reboot to Windows, ND-6500 now recognized as ND-6100a 0.01. It also showed up as SLAVE even though it was still on the IDE Master connector (hence Reverse ATA). I rebooted to DOS again and ran 6500MAIN.bat. Again â€“ a successful flash. Removed floppy and restarted computer to Windows XP. Now the drive it back to ND-6500a with the firmware 4.21. (The same as 2.21, but for Reverse ATA drives). I then downloaded Liggys 4.24firmware with bit setting and flashed it again, this time from windows. I set it to default DVD+R single & duel layer disks to DVD-ROM. Rebooted and checked to make sure everything was ok and then moved the ND-6500 to my Toshiba laptop. The Laptop now booted up ok and recognized the 6500 as SLAVE. I took a Dremmel tool and modded the faceplate to fit with my Toshiba and reinstalled it on the 6500 DVD burner. The 6500 faceplate is not as thick, so it sits a little deeper into the laptop, but I can live with that.
Now the testing begins.
