iDRAC7=> protect
protect - enable or disable FLASH write protection

Usage:
protect on  start end
    - protect FLASH from addr 'start' to addr 'end'
protect on start +len
    - protect FLASH from addr 'start' to end of sect w/addr 'start'+'len'-1
protect on  N:SF[-SL]
    - protect sectors SF-SL in FLASH bank # N
protect on  bank N
    - protect FLASH bank # N
protect on  all
    - protect all FLASH banks
protect off start end
    - make FLASH from addr 'start' to addr 'end' writable
protect off start +len
    - make FLASH from addr 'start' to end of sect w/addr 'start'+'len'-1 wrtable
protect off N:SF[-SL]
    - make sectors SF-SL writable in FLASH bank # N
protect off bank N
    - make FLASH bank # N writable
protect off all
    - make all FLASH banks writable
iDRAC7=> protect off all
