nboot.bin: 780x boot from on-chip ram, then this bin would be loaded,because nandflash first block size, this bin size must be minimized.
eboot.nb0: after nboot loaded, this really "wince bootloader" would be loaded.
xip.nb0: this bin include binfs, hive-based partition and user paition.
producer.nb0: this bin would be downloaded to netbook in factory producing, then run this bin, pc can download nboot.bin, eboot.nb0, xip.nb0 to the netbook.
2.Abort Fake RAM
DDR:also support 64MB DDR and 128MB DDR, you can buy one 128M micron DDR youself, and then find a package for 128M. I guess 128M micron DDR is too expensive.
SDRAM: support 128MB SDRAM.
This netbook already cracked, and all the files in xip.nb0 can be extracted. If someone want know more information, please tell me(EnitaLQ@hotmail.com). I will try my best to answer your question.
I want porting the linux to the netbook, if someone also has the ineresting, please follow me!!!
