Thanks Frank for the last message. Half of it sounded Greek, but I'll go home open the machine, and read it loud to it...Maybe it will let me understand how its inner parts works. I hope that seeing and touching will make things easier.

What is the procedure? After putting them in place, how/where do I tell DOS that I have them?<< Well, assuming they are the right pin configuration and such, the process is easy. Remember they should be a set of two identical chips, and should be inserted into a pair of twin slots. If there are only two slots left, the guess work is a no-brainer <g>. If not, try the next two available after the existing ones. Turn off the machine, snap them in place ( be sure they are seated firmly with a snap- you may have to do this once or twice if they don't take), and boot up the computer. Presto! While the machine is firing up, you should see the RAM amount scroll up to the new setting. The new number will look large for about a week. Then you start thinking about adding more <g>. It never stops. >>And another one: My motherboard can read only about 500 Mb of harddrive, but my disk actually is about 720. I know that you can cheat the machine and partition the disk in a way that DOS actually sees the remaining of that space as a second hard drive. Procedure please!<< Not sure about this one, Emil. DOS 6.2 can read up to a gig I recall. There might just be a simple change to be made to the BIOS> But I'd be careful with changing any setting in the CMOS. There's a chance you might lose data. If you know the manufacturer of the motherboard, it's possible that you can track down an upgraded BIOS for your system. That might do the trick. Otherwise, I think your only safe option is in a commercial program called Partition Magic. It supposedly can repartition the drive into different variations without the need to reformat (ie. lose data). I've never tried it. But folks who have say its worth the $49. It should do what you want, but with an old BIOS, there's no insurance. >>And another one: How easy/complicated is to install a SCSI card? What I mean by this is again where/how do I have to instruct the DOS to see it? or is the Win 95' plug and play ability to pick it up on the fly, and read it next time you turn the machine on?<< I've avoided Plug N Play, but have been around while it does its thing. Pretty straight forward. I'd recommend an Adaptec 2940 model or a BusLogic 445 SCSI card. Its rock solid and pretty much industry standard. It should have no problems with PNP unless you have some rogue hardware hiding inside. In Win 3.1 you would just insert it into the slot, turn on the machine and have a copy of the install disk on hand to install the driver. There's usually a little installation guide that comes with the card. I suspect that Win 95 would only vary in that it would first ID the hardware and then ask you for the appropriate disk. BTW be sure to get a SCSI card that fits your style buss slots (ie. IDE, VESA LOCAL, or PCI) Many 486 systems came with combos of IDE and VESA. If you can use the local bus, it will be much quicker than using the older IDE architecture. PS If you have a VESA system, I might have a card to sell.
