    Hi there,
    I had a lot of reading but still unsure about some DC's BIOS questions....

    1) Can the original bios chip be flashed? Is some soldering required before writing or Dreamshell is all I need to flash it?

    2) I understood there are at least 2 different DC's MB revisions: VA0 and VA1/2. One revision has 3.3 bios chip, the other 5v bios chip. The piggyback bios mod can be performed on both of them?

    3) Is it actually possible to have the DC with custom bios booting dreamshell from IDE HDD in slave mode, keeping the GD drive working just if desired inside the dreamshell? Or is the SD serial mod required in order to boot dreamshell?

    Thank so much, any help will be appreciated...
