Umm, OF quirks actually disgust us...
According to <sys/bootblock.h>, the Apple partition
map has
the following parameters:
---
struct apple_part_map_entry {
uint16_t pmSig; /* partition signature */
uint16_t pmSigPad; /* (reserved) */
uint32_t pmMapBlkCnt; /* number of blocks in partition map
*/
uint32_t pmPyPartStart; /* first physical block of
partition */
uint32_t pmPartBlkCnt; /* number of blocks in partition */
uint8_t pmPartName[32]; /* partition name */
uint8_t pmPartType[32]; /* partition type */
uint32_t pmLgDataStart; /* first logical block of data area
*/
uint32_t pmDataCnt; /* number of blocks in data area */
uint32_t pmPartStatus; /* partition status information */
uint32_t pmLgBootStart; /* first logical block of boot code
*/
uint32_t pmBootSize; /* size of boot code, in bytes */
uint32_t pmBootLoad; /* boot code load address */
uint32_t pmBootLoad2; /* (reserved) */
uint32_t pmBootEntry; /* boot code entry point */
uint32_t pmBootEntry2; /* (reserved) */
uint32_t pmBootCksum; /* boot code checksum */
int8_t pmProcessor[16]; /* processor type (e.g.
"68020") */
uint8_t pmBootArgs[128]; /* A/UX boot arguments */
uint8_t pad[248]; /* pad to end of block */
};

And the mkboothfs command in my latest patch puts the
following members:
---
memset(&pme, 0, sizeof(pme));
pme.pmSig = htobe16(APPLE_PART_MAP_ENTRY_MAGIC);
pme.pmMapBlkCnt = htobe32(1);
pme.pmPyPartStart = htobe32(1);
pme.pmPartBlkCnt = htobe32(1);
pme.pmDataCnt = htobe32(1);
strlcpy(pme.pmPartName, "NetBSD_BootBlock",
sizeof(pme.pmPartName));
strlcpy(pme.pmPartType, "Apple_Driver",
sizeof(pme.pmPartType));
pme.pmPartStatus = htobe32(0x3b);
pme.pmBootSize = htobe32(MACPPC_BOOT_BLOCK_MAX_SIZE);
pme.pmBootLoad = htobe32(0x4000);
pme.pmBootEntry = htobe32(0x4000);
strlcpy(pme.pmProcessor, "PowerPC",
sizeof(pme.pmProcessor));

Does any Mac guru know what values OF refers?
Anyway, I'd appreciate if someone try to create ISO CD-ROM
with modified mkboothfs by himself.
"make RELEASE=3.1_RC2 fetch && make
RELEASE=3.1_RC2"
in src/distrib/cdrom after applying my patch against the
netbsd-3
tree should just work. (rsync and mkisofs are required)
(I'm a bit tired to put ~180MB images again and again...)
