Step 3. Connect to VMware ESXi via SSH as root (replace <your_ip_address_or_hostname> with the correct ip)

ssh root@<your_ip_address_or_hostname>

Step 4. Get hardware information

esxcli hardware platform get

Identify and copy the UUID information

Step 5. Download the following image file

Step 7. Press the ENTER key twice after the screen below appears

Step 8. List the current directory contents

dir

EXAMPLE OUTPUT

IMPORTANT
Verify that you are inside the mounted virtual drive and that the contents in the screenshot are present

Step 9. Access “Online UUID Generator” website (https://www.uuidgenerator.net)

Step 10. Click on Generate a version 4 UUID

Step 11. Click on Copy

Step 12. Rename “smbios.txt” file

ren smbios.txt smbios.bak

Step 13. Create a new "smbios.txt" file and enter input mode

copy con smbios.txt

EXAMPLE OUTPUT

Step 14. Paste contents into “smbios.txt” file

IMPORTANT

1. Make sure to copy and paste the exact lines below (replace <product_name>, <serial_number>, <UUID> and <SKUNname> with the correct information)
2. Make sure to replace <UUID> with the string generated at Step 8

[System]
Manufacturer = Syneto
Product = <product_name>
Version = 1.00
SerialNum = <serial_number>
UUID = <UUID>
SKUNum = <SKUNname>

 

EXAMPLE

[System]
Manufacturer = Syneto
Product = Syneto-Hyper-3200-b
Version = 1.00
SerialNum = SYN0001DEV
UUID = 59ce383e-2f04-4953-83f0-55294b3a2478
SKUNum = HYPER3200

Step 15. Save smbios.txt file

CTRL + Z

ENTER

Step 16. Verify smbios.txt file contents

type smbios.txt

EXAMPLE OUTPUT

Step 17. Flash smbios.txt file

amidedos.exe smbios.txt

EXAMPLE OUTPUT

Step 18. Reboot the system

Step 19. Check the new UUID
