Problems with boot after kernel compilation (alpha platform)

["Carlos L.M." <adm_sis_(_at_)_yahoo_(_dot_)_es>]

Hi all,

 I have compiled a new kernel on a PowerStation 433au
with 128 MB RAM. When I try to boot, kernel can´t boot
because can´t find root partition. 

  How can I solve this ??

This is my dmesg with GENERIC kernel:
