Samsung B75S1 is an OEM LGA 1155 motherboard found in Samsung desktop systems (like the DB-Z205 or DB-Z400). While Samsung does not officially provide "patches," the community has developed several unofficial to overcome original hardware limitations. Common "Patches" & Modifications 16GB RAM Patch
: A known limitation where the BIOS only recognizes 8GB of RAM even if 16GB is installed. Users have found a workaround by enabling "Above 4G Decoding" "Memory Remap" option using a modded shell (e.g., modGRUBShell NVMe Booting
: Since the B75 chipset lacks native NVMe support, users "patch" the BIOS by inserting an NVMe EFI module using tools like . Alternatively, you can boot from a USB drive running Clover Bootloader to hand off to an NVMe drive. Unlocked Advanced Settings : Modifying the AMI Aptio BIOS
can reveal hidden PCIe and power management settings not visible in the standard OEM menu. Win-Raid Forum Motherboard Specifications
The Samsung B75S1 is a micro-ATX motherboard built on the legacy Intel B75 Express chipset. While originally designed for business-oriented stability, it has gained a second life in the budget PC building community through "patched" or modified BIOS versions. Key Specifications of the Samsung B75S1

Standard B75 motherboards, particularly OEM boards like those from Samsung, often come with restricted "locked" BIOS settings that limit hardware compatibility or feature sets. A "patched" Samsung B75S1 Samsung B75S1 is an OEM LGA 1155 motherboard
typically refers to a board using a Modified BIOS (ModBIOS) to achieve the following: Intel B75 Express chipset processor support - CPU-Upgrade

I understand you're looking for information about a patched BIOS or firmware for the Samsung B75S1 motherboard — but I need to be very careful here.
First, a quick clarification: There is no widely known Samsung desktop motherboard model "B75S1."
Samsung did produce some proprietary motherboards for their desktops (e.g., DP700A3D, DM series, or older B75 chipset-based systems). It's possible you meant:
However, if you're referring to a BIOS patch (e.g., to unlock hidden settings, add NVMe boot, enable newer CPUs, or remove boot restrictions), here’s what you should know: Samsung B75 chipset motherboard (maybe from a DM300/400
The B75 chipset only provides PCIe 3.0 x16 for the primary slot and PCIe 2.0 x4 for the second slot. If you add an NVMe adapter, your GPU will drop to x8 mode on some board revisions.
Prior to the patch, the B75S1 motherboard suffered from a known defect triggered by BIOS updates (specifically moving from older revisions to the B75S1 standard).
When enthusiasts search for “samsung b75s1 motherboard patched”, they are looking for a modified BIOS firmware file. A “patched” version typically includes:
