Q: Can I use an SSD with this motherboard?
A: Absolutely. The 2021 manual shows SATA port 0 (the one closest to the 24-pin power connector) supports AHCI mode. Enable AHCI in BIOS under Integrated Peripherals > SATA Mode.
Q: Where is the CLR_CMOS jumper?
A: Look for a 3-pin header labeled JBAT1 near the CMOS battery (CR2032). The 2021 manual includes a high-resolution PCB diagram on page 31.
Q: The manual PDF I found is only 12 pages, not 80. Is that correct?
A: No. The full ms7869 ver 10 motherboard manual 2021 is 92 pages long, including schematics and BIOS code tables. If your file is shorter, you have downloaded the Quick Start Guide, not the full service manual.
