Right next to the Intel Southbridge Controller we have the unused CN11 connector for SSD (page22). The schematic is as-seen from the underside of the motherboard:

The USB leads on the
CN11 are on the side closest to the Southbridge and numbered
Q4. A sketch from the top part of the motherboard is the following:

The last two leads
Q4 are placed slightly under the plastic glue that holds the Southbridge onto the motherboard (pins
1 on the previous sketch). It can be pushed aside slightly or cut and melted using a good cutter. The reason that you cannot connect to the bottom side of the motherboard to
CN11 is that the
HDD sits directly on top of it.
tnkgrl has an USB mod, but she pulls the leads from the SD connector directly from
RN42 (by grafting wires on top of the SD connector pins).

With the X50 turned on, press and hold the power button at the top of the unit. While holding the down power button, use the stylus tip to press the "Reset" button on the back. Allow the screen to fade to off. Release both buttons. The unit will power back on and display a menu to confirm the hard reset request. The Axim will be hard reset, just as it was when it left the factory.
During the era (cca. 1993/4 the 2GB limit was prevalent in DOS before Windows95 OSR2 hard-drives that supported over 2GB limits, a 63-sector program called OnTrack sat as a DOS TSR and translated hard-drive calls by 63-sectors.
In Linux, using
fdisk, assuming that the drive is
/dev/sdb we can list the partition table and get something like:
Device Boot Start End Sectors Size Id Type /dev/sdb1 * 9 5032943 5032935 2.4G 54 OnTrackDM6
To mount that partition directly, we can issue:
mount -o ro,loop,offset=64512 -t vfat /dev/sdb /mnt
Another approach is to use
umount /mnt losetup /dev/loop0 /dev/sdb -o 32256 fdisk -l /dev/loop0
which should list all partitions. For instance:
Device Boot Start End Blocks Id System /dev/loop0p1 * 63 4128704 2064321 6 FAT16 /dev/loop0p2 4192965 16434494 6120765 5 Extended /dev/loop0p5 4193028 8385929 2096451 6 FAT16
So, to mount
/dev/loop0p5 we would calculate and then mount the partition:
losetup -d /dev/loop0 losetup -o 2146862592 /dev/loop0 /dev/sdb mount -t vfat /dev/loop0 /mnt
