Has the ISO been updated to patch B yet?

I have machines with a CD but no HD, and they also do not have a PCI bus so
the normal (pre-patch B) startup hangs. Has the ISO been updated to have the
new startup code that doesn’t do a PCI buss check? Alternatively, has the
dinit really been updated in patch B, because when I try it I still get the
same errors on trying to boot from either a ATA Flash drive or PCMCIA hard
drive that I got with previous versions where dinit formatted it as if it
was a floppy…
