Hi Al,

http://www.bitsavers.org/bits/Unisoft/V.1.5+/sys/h/sys/d_profile.h Line 72
#define MAXBLOCK 19455 /* Last sector on disk */

Size of 10Mb Profile is hardcoded, put this as 2^24 as that's maximum of Profile protocol (3 bytes)

http://www.bitsavers.org/bits/Unisoft/V.1.5+/sys/pro.c Lines 45 to 60
struct prlmap {

	daddr_t	pm_beg;		/* Base address in blocks */
	daddr_t	pm_len;		/* Number of blocks in logical device */
} prlmap[] = {
/* a */	{PRNSWAP+101,	16955},	/* root filesystem on 10 Meg. disk */
/* b */	{101,	PRNSWAP},	/* swap area (2400 blocks) */
/* c */	{PRNSWAP+101,	7227},	/* root filesystem on 5 Meg. disk */
/* d */	{9728,	9728},		/* 2nd filesystem on 10 Meg. disk */
/* e */	{0,	0},		/* unused */
/* f */	{0,	7168},		/* old root filesystem (old a) */
/* g */	{7168,	2496},		/* old swap (old b) */
/* h */	{101,	19355},		/* f.s. using entire 10 Meg. disk */

};

/* THESE MAY REPLACE f AND g ABOVE */
/* f 	{4101,	15355},		/* alternate root f.s. on 10 Meg. disk */
/* g 	{101,	4000},		/* alternate swap */

It seems they hardcoded the partition map for 5Mb and 10Mb disks.

But I don't find any kind of reference of it using that partition map. Maybe that source is in the disklabel tool :p

Check out what happens changing MAXBLOCK and maybe then you can create additional partitions.
