>Description:
	
Booting with the April28th -current bootblock_com0 (or bootblock) results in
an error when accessing the partition (via "dir", or when typing "boot").  The
error reported (sorry, didn't copy down the exact error) was basically an "out
of space" error, and referenced things such as "(heap+49533)".

Increasing the defined heap size in the i386 makefile from 5000 to 10000 solved
the problem for me (t'was a shot in the dark, but it worked).

In particular, this happened when attempting to boot on a 120G EIDE drive
installed on an ATA/100 PCI controller.

>How-To-Repeat:
	
Install the bootblock, and try and boot. ;-)
>Fix:
	
In /usr/src/sys/arch/i386/stand/biosboot/Makefile, change the line:

SAMISCCPPFLAGS+= -DHEAP_START=0x20000 -DHEAP_LIMIT=0x50000

to

SAMISCCPPFLAGS+= -DHEAP_START=0x20000 -DHEAP_LIMIT=0x100000
