Re: How to Properly Install and Use TOS 7 on the 425 Plus Series TNAS
Hi CursaYang,
Thanks for the confirmation. I have a general question regarding the BIOS update procedure itself for future reference.
The instructions always state that all drives must be removed before flashing the BIOS. Since removing NVMe drives from the motherboard is quite tedious compared to standard SATA drives, I would like to ask: why is it strictly necessary to remove them?
Is it merely a general safety precaution to protect user data in case of a flash failure, or does having the NVMe drives installed actually interfere with the BIOS flashing process or the subsequent boot/PCIe initialization?
Thanks for explaining!
