Well, keeping it short. Couldn’t find all clover’s boot args, so here goes the list:

At this section you can add “Boot Flags” and “Kernel Flags” to be used by the system…

Clover – This is a bootloader writer which can allow you to customize certain conditions so that you can boot your Mac operating system in a Hackintosh. Plist – Some configuration to allow the initial installation of the Mac USB to complete booting up. Clover Configurator- A program that will create a plist.

Hackintosh Safe Mode Clover

Here we will list only Clover’s proprietary “Boot Flags”, different flags, like for example,npci=0x2000, npci=0x3000, darkwake=0, etc…, should work as expected…

Flag	Action
WithKexts	Boot OS X loading System Kexts and ignoring kernelcache.
-v	Verbose Boot.
-s	Boot OS X into Single User Mode.
-x	Boot OS X into SafeBoot (Safe Mode).
MountEFI=yes/diskX	Mount EFI partition at every boot or from disk X (X = disk number).
LogLineCount=0	Set maximum number of lines for log file, default 0 (no Limit).
LogLocation=PATH	Set the path for the log files to be saved.
LogEveryBoot=Yes/No	Save log files at every boot.

Here’s a completish guide though:

Part of Device Path - Also shown in Clover's logs. LastBootedVolume - The last booted volume will be set as default one in Clover GUI. OS X Startup Disk can be used to reboot into another volume, but for the following reboot DefaultVolume will be used again.
Secondly, safe mode can be useful for recovery purposes. If you install a kext that breaks your system, you can boot into safe mode and remove it. If you are having issues booting your computer, you should generally try safe mode just to see if it works, and because debugging a running computer is a lot easier.

Troubleshooting

If you are having any trouble, first try this string. It works on a lot of systems with Intel HD Graphics to get into the OS X Installer from a Unibeast USB.

If you have an NVIDIA Desktop GPU, use this string to boot into the installer:

If all else fails, or you don't know where to start, use this string:

If you have an NVIDIA Desktop GPU and you've installed NVIDIA Web Drivers, use this string:
