Hello everyone.Today i am searching for some kernel gurus that can anwser some questions about 2.6 kernel.My default 0.5 AL kernel was 2416582 b and since everyone is talking for custom kernel which boost you system i have compiled my own which now after deep searching of the kernel conf one by one i have 1369916 b. But there are some options which i dont know if i really need them .So here it goes:
1)Bus options->PCI support->PCI device name database <- do i need this?
2)is it safe to disable kernel support for a.out end ECOFF binaries ?
3)ATA support->CMD640 chipset -do i need it? i dont have this chipset onboard
4)RZ1000 chipset bugfix/suport
5)what level of information will "compile the kernel with frame pointer" give me?is it safe to disable?
6)do i really need these
crc32 functions
preemptible kernel
code maturity
7)if i dont use harddisk shutdown or the sleep function or the monitor auto-power off do i have to use ACPI only for shutting down the PC?
i hope someone will help.
Thanks

1) As the helps says, not really, but it doesn't hurt either. I would keep it.
2) yes
3) no, you don't need it.
4) if you don't have it, you don't need it.
5) Safe to disable, it's only useful if you are going to debug the kernel.
6) crc32: It is enabled most of the time automatically. Won't hurt to enable it though.
You don't need a preemptible kernel, but it is nice to have.
Code maturity is only a setting to manage how much options you see, and you want it because you may want to enable some of the "immature" options.
7) Yes, you need acpi or apm for powering your pc down. You don't need to run any acpi or apm daemon though. Make sure your bios options match your kernel options.
In general reading the help in menuconfig should give you enough info to make a sane decision.

If your running a desktop system, which you are I would enable preemptible kernel. It will make your GUIs a lot smoother than it being disabled
