To upgrade from 128KB cache to 256KB, you need to add four 28-pin modules (32K x 8, 25ns SRAM) and replace the existing TAG module with one 28-pin TAG (32K x 8, 20ns SRAM).
To upgrade from 0KB cache to 128KB or 256KB, you need to add either 4 (for 128KB) or 8 (for 256KB) 28-pin modules (32K x 8, 25ns). You also need to add a TAG module (32K x 8, 20 ns SRAM for 256KB or 8K x 8, 20 ns SRAM for 128KB)
Cache memory jumpers are preset at the factory for 0/128KB of cache. If you are installing 256KB, reset the jumpers by moving them forward to cover the two jumper pins.
Regular system memory is upgraded with Industry Standard 72-pin 36-bit parity SIMM chips. Each socket can support a 2, 4, 8 or 16 MB SIMM.
All machines came with a 2400bps data modem. All 2155 and 2168 (except for the 2155D53) had a data/fax modem with 9600bps send and 4800bps receive capability on the fax side.
Video drivers for these machines are available on IBM's FTP site at ftp://ftp.pc.ibm.com/pub/ps1aptiva/drivers/video/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.
Phone Support for these machines is available from IBM on a fee basis over the IBM Club's 900# (1-900-555-2582). The first minute of this call is free, each additional minute is charged to your phone bill at a rate of $2.99/minute.
