Regular system memory is upgraded with 36-bit or 32-bit (parity or non-parity) industry standard 70ns 72-pin SIMM chips. If the machine has 2 SIMM sockets, it can handle up to a 32MB SIMM in each socket. If it has 4 SIMM sockets, it can handle up to a 16MB SIMM in each socket.
Video drivers for these machines are available on IBM's FTP site.
You can download the Windows 3.1 driver for the CL-GD5428 chipset at ftp://ftp.infania.net/pccbbs/ps1/c5426_28.exe
All of these machines use a standard IDE controller. This interface should support any standard IDE device. Some Enhanced IDE (EIDE) devices (namely hard drives larger than 528MB) may be able to function with the use of disk overlay software, normally supplied by the drive manufacturer, but is not supported by IBM. Though EIDE CD-ROMs are not supported on these machines, a CD-ROM with it's own ISA interface controller should work. Any ISA card (CD-ROM controller, modem, SCSI card) added to these machines needs to be non-"Plug and Play" to help insure compatability.
Machines that are capable of video memory upgrades require a 40-pin ZIP DRAM module configured as 256K x 16, which gives an additional 512K of video memory.
