+IA-64 system type
+CONFIG_IA64_GENERIC
+ This selects the system type of your hardware. A "generic" kernel
+ will run on any supported IA-64 system. However, if you configure
+ a kernel for your specific system, it will be faster and smaller.
+
+ To find out what type of IA-64 system you have, you may want to
+ check the IA-64 Linux web site at http://www.linux-ia64.org/.
+ As of the time of this writing, most hardware is DIG compliant,
+ so the "DIG-compliant" option is usually the right choice.
+
+ HP-simulator For the HP simulator (http://software.hp.com/ia64linux/).
+ SN1-simulator For the SGI SN1 simulator.
+ DIG-compliant For DIG ("Developer's Interface Guide") compliant system.
+
+ If you don't know what to do, choose "generic".
+
+Kernel page size
+CONFIG_IA64_PAGE_SIZE_4KB
+
+ This lets you select the page size of the kernel. For best IA-64
+ performance, a page size of 8KB or 16KB is recommended. For best
+ IA-32 compatibility, a page size of 4KB should be selected (the vast
+ majority of IA-32 binaries work perfectly fine with a larger page
+ size). For Itanium systems, do NOT chose a page size larger than
+ 16KB.

+Enable Itanium A1-step specific code

+ you probably don't and you can answer "no" here.
+
+Enable Itanium B-step specific code
+CONFIG_ITANIUM_BSTEP_SPECIFIC
+ Select this option to build a kernel for an Itanium prototype system
+ with a B-step CPU. You have a B-step CPU if the "revision" field in
+ /proc/cpuinfo has a value in the range from 1 to 4.
+
+Enable Itanium B0-step specific code
+CONFIG_ITANIUM_B0_SPECIFIC
+ Select this option to bild a kernel for an Itanium prototype system

+Force interrupt redirection

+ redirect interrupts to different CPUs. Select N here if you're
+ unsure.
+
+Enable use of global TLB purge instruction (ptc.g)
+CONFIG_ITANIUM_PTCG
+ Say Y here if you want the kernel to use the IA-64 "ptc.g"
+ instruction to flush the TLB on all CPUs. Select N here if

+
+Enable SoftSDV hacks
+CONFIG_IA64_SOFTSDV_HACKS
+ Say Y here to enable hacks to make the kernel work on the Intel

+Enable AzusA hacks
+CONFIG_IA64_AZUSA_HACKS
+ Say Y here to enable hacks to make the kernel work on the NEC
+ AzusA platform. Select N here if you're unsure.
+
+Force socket buffers below 4GB?
+CONFIG_SKB_BELOW_4GB
+ Most of today's network interface cards (NICs) support DMA to
+ the low 32 bits of the address space only. On machines with
+ more then 4GB of memory, this can cause the system to slow
+ down if there is no I/O TLB hardware. Turning this option on
+ avoids the slow-down by forcing socket buffers to be allocated
+ from memory below 4GB. The downside is that your system could
+ run out of memory below 4GB before all memory has been used up.
+ If you're unsure how to answer this question, answer Y.
+
+Enable IA-64 Machine Check Abort
+CONFIG_IA64_MCA
+ Say Y here to enable machine check support for IA-64. If you're
+ unsure, answer Y.
+
+Performance monitor support
+CONFIG_PERFMON
+ Selects whether support for the IA-64 performance monitor hardware
+ is included in the kernel. This makes some kernel data-structures a
+ little bigger and slows down execution a bit, but it is still
+ usually a good idea to turn this on. If you're unsure, say N.
+
+/proc/pal support
+CONFIG_IA64_PALINFO
+ If you say Y here, you are able to get PAL (Processor Abstraction
+ Layer) information in /proc/pal. This contains useful information
+ about the processors in your systems, such as cache and TLB sizes
+ and the PAL firmware version in use.
+
+ To use this option, you have to check that the "/proc file system
+ support" (CONFIG_PROC_FS) is enabled, too.
