The MB Wont reconise a primaster master or a secondary master, Just primary slave and secondary slave. The HD I put in has 2k on it, With a diffrent cpu core install. So of course that wont work. So i try to boot up the computer off the cd rom so i can do a reinstall, But it will go to Boot from ATAPI CD-ROM: And just sit there, Every so often reading the cd rom, But then after about 30-45 Minutes it gives some off TRAK error msg i never seen before. About the slave/master problem, I tryed all diffrent jumper settings, IDE Ribbons ect. Diffrent CD Rom's as well. Then i figured i would try and boot from a floppy even though i sworn them away a few years ago. But the Floppy connector is a non-standard port, Instead of the 2nd pin being the blank, Its 2 pins in. So i cant boot off a floppy, I cant boot off the CDROM and i cant boot off the hd.....I even tryed booting from a jump drive, But the bios doesnt have the option to boot off of a USB Device. And of course i cant flash the bios becuase i got no floppy drive...Anyone got any answers? Or am i just SOL. -NeoTremer

"The HD I put in has 2k on it, With a diffrent cpu core install. So of course that wont work" It should boot regardless. You may have problems related to different hardware, but it "should" boot. It sounds like you're either not configuring the drives correctly, or there's a problem with the board's IDE controller. My guess is, it's a configuration problem. 1st of all, make sure you know which jumper is which. You don't say how many total IDE devices you have, but if it's just 2 (HDD & CD-ROM), the HDD should be primary master & CD-ROM should be 2ndary master. Do NOT use the cable select jumper...use the MASTER jumper only. Some HDDs have a different jumper setting when the drive is a master w/o slave, or master w/slave. The settings should be printed on a label on the top of the HDD. If not, go to the manufacturer's website & see if you can find a diagram.
