You just need to get the jumpers right. Your P2 might not take advantage of ATA 100/133, however. This depends on the IDE controller. It will run but not at its full performance level. You also did not mention your OS so, being an older rig, I am guessing Win98. Now, if the games are directed to install on the slave drive, keep in mind that some files will be placed on the master anyway. How much is anyones guess but make sure you have some room there too. Another option might be to boot between the drives by switching them in the BIOS for gaming sessions. This would require installing an OS on the drive, however. It might actually be a safer way to do this so as to not risk impairing your 10 gig drive. Good luck with your project.
Have older gateway pent 2 400 mhz 10 gb h/d 5200 rpm,400 ram, installed would like to install another 50 or 60 gb 7200rpm, as a seconded, for children to use for games, not sure of what ata 100 or 133 exactly means or the terms EIDE or IDE means,or if I really need to worry about it, am leaving the small h/d as o/p sys, with the larger one as the slave with their game pro`s installed on it.
I believe I`m heading in the right way here ? Any one help out an old firefighter here thanks.
