Upgrading Memory

Q: My computer had 32 MB of memory consisting of 4 8MB chips installed on a SIMM. I wanted to increase it to 128MB so I bought 4 32MB chips on a SIMM and installed it in place of the 32 MB. The computer would recognize only 64MB of RAM. How can I get it to recognize the full 128MB of RAM?

Response 1: Some motherboards have a specific sequence in which memory modules must be added. I presume you consulted the motherboard manual about this?

Answer: Yes I did. I used slots 1 & 2 on the motherboard.

Add-on to Response 1: What I mean is: 32MB in Slot 1 and 128MB in Slot 2 = 160MB, may not be a recognizable configuration to your motherboard. Order of installation may be important.

Response 2: Sometimes memory SIMMs are difficult to seat properly in their slots. Are you sure they were properly installed?

Answer: Yes the slots were very difficult to access and I have the broken fingernails to prove it. I am sure they were seated properly.

Response 3: In my experience some motherboards do not properly recognize the memory modules of some manufacturers. That may be your problem. Suggest having the memory module provider install them.

CD-ROM Implies CD-ROM Disk Empty

Q. I can't get my CD-ROM drive to recognize that there is anything on the CD-ROM disk which I bought at the last meeting. I am not convinced that there is anything on the disk.

Response 1: How old is you CD-ROM drive? It may be too old to recognize the latest CD formatting configuration now used by all CD-ROM drives.

Q. You mean there has been a change in CD format? I think this is an 8x (speed) drive which I got in 1997.

Response 2: If it isn't able to recognize disks formatted and written to using the ATAPI standard you won't be able to use it with such disks. Your only recourse is to get a new CD-ROM drive with that capability.
Maybe, maybe not. Check out sites like those below.

More Than You Wanted To Know Dept.
ATAPI = Advanced Technology Attachment Packet Interface
Some manufacturers provide a CD-ROM Drive with an ATAPI/IDE interface allowing an 8x CD-ROM drive to be connected to the IDE cabling used for the Hard Drive. Click here. See also Seagate's site.
The controlling electronics for IDE drives are self-contained not on a separate board.
IDE = Integrated Drive Electronics *most common
IDE = Imbedded Drive Electronics
