Looks like I'm unable to boot from "PCMCIA ATA Flash Card":

Will try to boot from :

I did following:
Downloaded "install-media-10.2R3.10-export" file from Juniper Support
page and verified MD5 hash:
root at ubuntu:/media# md5sum /media/martin/install-media-10.2R3.10-export
445b2820c1d67b8219d855aa7009ce4f /media/martin/install-media-10.2R3.10-export
root at ubuntu:/media#
..zero-filled my CF card(it's 1GB "SiliconDrive CF", Juniper original)
which I will use for "PC Card" adapter(SanDisk CompactFlash PC Card
Adapter):
root at ubuntu:/media# dd if=/dev/zero of=/dev/sdb bs=10M
dd: writing `/dev/sdb': No space left on device
100+0 records in
99+0 records out
1047674880 bytes (1.0 GB) copied, 1096.18 s, 956 kB/s
root at ubuntu:/media#
..and copied install-media-10.2R3.10-export to blank /dev/sdb using dd(1):
root at ubuntu:/media# dd if=/media/martin/install-media-10.2R3.10-export
of=/dev/sdb bs=64k
5199+1 records in
5199+1 records out
340752384 bytes (341 MB) copied, 356.629 s, 955 kB/s
root at ubuntu:/media#
..and verified, that MD5 hash of /dev/sdb is the
same(445b2820c1d67b8219d855aa7009ce4f) as on Juniper web-site:
root at ubuntu:/media# dd if=/dev/sdb of=/media/verification2 bs=512 count=665532
665532+0 records in
665532+0 records out
340752384 bytes (341 MB) copied, 358.987 s, 949 kB/s
root at ubuntu:/media# md5sum /media/verification2
445b2820c1d67b8219d855aa7009ce4f /media/verification2
root at ubuntu:/media#
As you can see, it did. According to fdisk(8) and file(1), everything
seems to be fine as well:
root at ubuntu:/media# fdisk -l /dev/sdb
Disk /dev/sdb: 1047 MB, 1047674880 bytes
1 heads, 1 sectors/track, 2046240 cylinders, total 2046240 sectors
Units = cylinders of 1 * 512 = 512 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/dev/sdb1 645053 665532 10240 4 FAT16 <32M
/dev/sdb2 * 521 645052 322266 a5 FreeBSD
Partition table entries are not in disk order
root at ubuntu:/media# file -s /dev/sdb
/dev/sdb: x86 boot sector; partition 1: ID=0x4, starthead 0,
startsector 645052, 20480 sectors; partition 2: ID=0xa5, active,
starthead 0, startsector 520, 644532 sectors
root at ubuntu:/media#
In addition, if I put this very same "PCMCIA ATA Flash Card" to a
working Juniper, following messages are printed to the
/var/log/messages:
Feb 10 16:07:06 /kernel: ata2: <SILICONSYSTEMS VER2.00> at port

..however, there is no "ad3" under "show system storage":
root> show system storage | match ad3

Any ideas, what might cause RE-850 not to boot from this "PCMCIA ATA
Flash Card"?
