Build TomElliott Kernel
PRE BUILD ENVIRONMENT IS ASSUMED ALREADY INSTALLED ON THE SYSTEM YOU'RE BUILDING NOTE: It is assumed you have root access to the system you're building this on. It also assumes you know your CWD (Current Working Directory).

Build TomElliott Kernel for FOG 0.32 and earlier
The below instructions are to build the TomElliott kernel. There is an extra step involved compared to the normal kernel build as there are firmware's built directly into the kernels now.
Download the Kernel
As of the time of this writing kernel 3.13 is the latest. You can use previous, or future kernels as well though.
wget https://www.kernel.org/pub/linux/kernel/v3.x/linux-3.13.tar.xz
Uncompress the kernel
tar -xf linux-3.13.tar.xz
Go into uncompressed linux kernel directory
cd linux-3.13
Get the config file
wget https://svn.code.sf.net/p/freeghost/code/trunk/kernel/TomElliott.config.32 -O .config
Download the prerequisite package (THE EXTRA STEP IS HERE)
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Prepare the build
make ARCH=i386 menuconfig
Add any choices, or don't but when you exit, it will ask you to save the config, NEEDED.
After you've saved the config.
Build the bzImage
make ARCH=i386 bzImage
This will take a while. Once successful, it will say bzImage created.
Copy the built kernel to your FOG Server's kernel directory.
NOTE: In my example, the FOG Server is the same as my build system. NOTE: Recommend to make a backup of the original /tftpboot/fog/kernel/bzImage before continuing just in case.
cp arch/x86/boot/bzImage /tftpboot/fog/kernel/bzImage
Build TomElliott Kernel for FOG 0.33b and newer
The below instructions are to build the TomElliott kernel. There is an extra step involved compared to the normal kernel build as there are firmware's built directly into the kernels now.
Download the Kernel
As of the time of this writing kernel 4.17 is the latest. You can use previous, or future kernels as well though.
wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.17.tar.xz
Uncompress the kernel
tar -xf linux-4.17.tar.xz
Go into uncompressed linux kernel directory
cd linux-4.17
Get the config file
To Build 32 bit Kernel
wget -O .config https://github.com/FOGProject/fos/raw/master/configs/kernelx86.config
To Build 64 bit Kernel
wget -O .config https://github.com/FOGProject/fos/raw/master/configs/kernelx64.config
Download the prerequisite package (THE EXTRA STEP IS HERE)
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
Prepare the build
To Build 32 bit Kernel
make ARCH=i386 oldconfig
To Build 64 bit Kernel
NOTE: MUST BE ON A 64 BIT OS
make oldconfig
In case you want to make changes to the config run:
make ARCH=i386 menuconfig
or
make oldconfig
Make sure to save when exiting the menuconfig.
Build the bzImage
To Build 32 bit Kernel
make ARCH=i386 bzImage
To Build 64 bit Kernel
make bzImage
This will take a while. Once successful, it will say bzImage created.
Copy the built kernel to your FOG Server's kernel directory.
NOTE: In my example, the FOG Server is the same as my build system. NOTE: Recommend to make a backup of the original /var/www/html/fog/service/ipxe/bzImage before continuing just in case.
cp arch/x86/boot/bzImage /var/www/html/fog/service/ipxe/bzImage
or
cp arch/x86/boot/bzImage /var/www/html/fog/service/ipxe/bzImage32
Additional Patches
Edit the files within the linux decompressed folder:
drivers/net/usb/r8152.c
Search forREALTEK_USB_DEVICE(VENDOR_ID_REALTEKand add this line:
{REALTEK_USB_DEVICE(VENDOR_ID_MICROSOFT, 0x0927)}
drivers/scsi/storvsc_drv.c
This is an important patch to help prevent from major performance issues in HyperV: https://forums.fogproject.org/topic/6695/performance-decrease-using-hyper-v-win10-clients
Search forblk_queue_virt_boundary
Delete the line and add:
if (PAGE_SIZE - 1 < 4096) {
blk_queue_virt_boundary(sdevice->request_queue, 4096);
} else {
blk_queue_virt_boundary(sdevice->request_queue, PAGE_SIZE - 1);
