For further placement rules, refer to “#2844 PCI IOP” on page 252.
Minimum operating system level: OS/400 V5R2
The #281x ATM, #2750, #2751, #2761, and #4761 are not supported after OS/400 V5R2.
The #2844 is a Customer Install Feature.

#2890 PCI Integrated Netfinity Server, #2891 PCI Integrated xSeries Server, #2899 PCI Integrated xSeries Server
The #2890 PCI Integrated Netfinity Server contains a 700 MHz processor. The #2891 PCI Integrated xSeries Server
contains an 850 MHz processor. The #2899 PCI Integrated xSeries Server contains a 1 GHz Pentium III processor. Each
processor contains four memory slots in the xSeries IOP.
Each main storage slot of the #2890, #2891, or #2899 can contain either a 128 MB, 256 MB, or 1024 MB xSeries server
main storage card, providing a total main storage capacity ranging from 128 MB to 4096 MB (4 GB). Allowable main storage
increments in MB are: 128, 256, 384, 512, 640, 768, 896, 1024, 1152, 1280, 1408, 1536, 1664, 1792, 2048, 2176, 2304,
2432, 2560, 3072, 3200, 3328, and 4096. A minimum of 128 MB xSeries IOP memory is required. When the maximum
memory is installed, only 3712 MB is addressable.
The following main storage cards provide server memory for the #2890, #2891, and #2899:
#2895 - 128 MB Server Memory (withdrawn from marketing on 19 November 2004)
#2896 - 256 MB Server Memory (withdrawn from marketing on 19 November 2004)
#2897 - 1 GB Server Memory
