booting problems

hello!

I have a problem booting netbsd with default boot1.fs and boot2.fs boot 
floppies. Computer freezes when it outputs it's last boot msg -
 stray  interrupt 7 - but there is no interupt 7 on system. Interesting is 
that boot-small.fs is working, but it doesn't have support for advansys 
scsi adapter. 
Can anyone can be so kind and make me custom boot install disk with eisa, 
pci and isa support, advansys scsi support, 3com Boomerang ethernet 
support, rt8139c and possibly smp - i586?

thank you, gorazd
