A minimal kernel for me will not be a minimal kernel for you. There are dozens of wireless drivers, network drivers, hard disk drivers, graphic drivers, interface drivers, protocol drivers... Enabling them all will not be minimal.

Tick off the options that apply to your system in make menuconfig. View the help options (? key) for anything you don't immediately understand. Lots of things you need will be ticked off already; a lot of what you do will be removing what you don't. If it doesn't work, google the error and find out why. Never build disk drivers as modules, since you can't load your disk driver from disk. Your SATA probably uses the AHCI driver but don't take my word for it. I hate to suggest trial and error but your first time building a kernel will have to be spent getting used to the idea of checking what you need.

crda

CRDA(8) 							       Linux								   CRDA(8)

NAME

       crda - send to the kernel a wireless regulatory domain for a given ISO / IEC 3166 alpha2

SYNOPSIS

       crda

Description
       crda is the Linux wireless central regulatory domain agent.  crda is intended to be used by udev scripts and should not be run manually
       unless debugging udev scripts.  crda is triggered to run by the kernel by sending a udev event upon a new regulatory domain change. Regula-
       tory domain changes are triggered by the wireless kernel subsystem (upon initialization and on reception of country IEs), wireless drivers,
       or userspace (see iw ). Upon a regulatory domain change the kernel sends a udev change event for the regulatory platform. The kernel
       ignores regulatory domains sent to it if it does not expect them. The regulatory domain is read by crda from the regulatory.bin file.

RSA Digital Signature
       If built with openssl or gcrypt support crda will have embedded into it an RSA digital signature which will prevent it from reading cor-
       rupted or non-authored regulatory.bin files. Authorship is respected by the RSA public key packed into crda.  This specific crda package
       has been built with an RSA public key from John Linville (the Linux wireless kernel maintainer) and as such will only read regulatory.bin
       files signed by him. For further information see the regulatory.bin man page.

UDEV RULE

       A udev regulatory rule must be put in place in order to receive and parse udev events from the kernel in order to get udev to call crda
       with the passed ISO / IEC 3166 alpha2 country code.  An example udev rule which can be used (usually in /lib/udev/rules.d/85-regula-
       tory.rules ):

       KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/crda"

Environment variable
       Set the COUNTRY environment variable with a specific ISO / IEC 3166 alpha2 country code and then run crda without arguments. This will send
       a regulatory domain for that alpha2 to the kernel.
