Update Bootloader for LPC2148

[NaserKshirsagar]

Hello Sir/Madam,
I am trying to update secondary bootloader for LPC2148. I have got a compiled hex file for the same. But in flashmagic, in ISP option, if I select LPC2148 as micro controller it disables "Update Bootloader" Menu.
Is there any other way to do it?

The "update bootloader" is for the 89V51Rx2 family. You simply need to program your hex file to the start of flash memory. On reset it will execute.
