[rtems] question about VBR

[Stan]

hello,

Anyone can explain how Efi68k bsp use 'pseudo' VBR ?
I know that vector table CPU hold address in RAM (which hold JMP + add : 6 bytes);
As for the rest...

How Rtems use this table in ram with _CPU_ISR_install_vector and _CPU_ISR_install_raw_handler ?

Can you explain me that ?
Thanks.

Stan.
