Cold BootLoad
After a "hard" power cycle (both batteries removed), there is nothing left in
the DRAM of the NetBook and the Loader (located on the FLASH/DRAM module) has
to load an "EPOC ARM ROM" format image.
Two methods of getting the binary boot image:
- Serial Bootstrap
This is simply a YMODEM transfer of a binary image with the serial settings
of 115200 baud, no parity, 8 data bits and 1 stop bit. The unix "sb" command
works fine as does a copy of the old DOS telix program. Note that even at
115200, it takes about half a hour to upload the default 12 Mbyte EPOC 5
image.
- CF Bootstrap
Loads a file os.img from a FAT formatted CF card. This is much
faster (about 20 sec. vs 30 min.) way to boot large images. The FAT
compnetatability seems quite good as reads cards formatted and written from
the NetBook itself, my Kodak DC265 Camera, IBM PCDOS 7, Linux mtools and
Linux fatfs.
