    Greetings,

    I recently purchased a Dell Latitude Z600. It has two internal SSD's but only allows you to select IRRT, which is effectively RAID 1. I would like to update the option ROM to enable the option to use RAID 0.

    The laptop uses the ich9m-e chipset, which supports RAID 0/1/5.

    Is it possible to modify the bios to allow this functionality? Alternatively, can the HDR package be modified to include a different Intel Option ROM? I saw a post where a guy did this for a Vostro: LINK (unable to link, it's on TheLostBrain)

    Here is a link to the bios itself: Can't link, Dell z600, Z600_A02.EXE

    Thanks in advance.

    IMO, it's doable. I can try to create a BIOS for you with full RAID module.
    But before I do anything - please check thread how to recover you laptop from bad BIOS flush AND do it. I.e. try to downgrade your BIOS to previous BIOS revision just to make sure it actually works!

    Edit: I've responded too fast...
    I haven't seen such huge BIOS file before - it's even aligned differently.
    I cannot identify all blocks properly yet.
    Although, I can see the module you want to replace Intel(R) RAID for SATA - v8.0.0.1039
    It's size 66560 bytes. I seemed to recall, striped RAID ROMs are about 40-45KB, and full like 60-65KB
    I.e. it looks like you have full one already.
    Do you have "Intel(R) RAID for SATA" full ROM handy - just want to check its size.

    Edit again:
    Yep - you have striped ROM...
    My data were old:
    "Mirror only" Intel(R) RAID for SATA - v7.5.0.1017 58368 bytes
    "Full" Intel(R) RAID for SATA - v7.5.0.1017 65536 bytes

    BTW: Do you have full "Intel(R) RAID for SATA - v8.0.0.1039"?

    Thanks for the intrest and research thus far.

    I can't speak to the ROM sizes other than the version currently in the update does have "IRRT", Intel Rapid Recovery Technology, or just a fancy name RAID 1 with some on-demand capabilities:

    I'm attempting to revert to version A01 now...

    I was able to downgrade to A01 from A02 and re-update to A02.

    It does a CRC check, flashes the System ROM then the Keyboard Controller ROM.

    Here are some pics.

    Option screen, only choice available under RAID Type is "Recovery": IMG00006-20091229-0802.jpg

    Cool. And you did it AS BIOS recovery procedure. I.e. fiddling with power, etc., right?

    I got few Intel(R) RAID for SATA ROMS
    8.0.0.1038.bin
    8.0.0.1039 striped.bin <- yours
    8.5.0.1030.bin <- the same one you mentioned

    I still need to research on Z600 BIOS structure – I doesn’t match what I’ve seen so far.
    Will keep you posted.

    Actually, no, I didn't try that method.

    The machine itself seems to be having issues. Screen is garbled.

    Called Dell and they want me to send it in for service. Since they won't allow RAID0 as an option and it broke after 1 week, I'm sending it back permenantly and getting a refund. Pretty disappointing since running the two SSD drives in RAID0 would have been super fast. The chassis is very thin for a machine of this size, which made it easy to carry so it's a real shame.

    I've ordered a Lenovo Thinkpad 400s as a replacement.

    Thanks for the assist. I'll point some other people over here who might want the same modded BIOS.

    I modified the latest Latitude E6400 (A34) update to include the Intel RAID option rom (8.0.0.1039 - ICH9M-E) from the latest Latitude M6400 (A13) uppdate which allows you to set RAID 0 / RAID 1 / RECOVERY modes in the raid menu (CTRL-I).

    Got it running on my E6400 with 2 128 ssd's

    Maybe someone else finds it useful :)

    This is awesome, all safe and no issues? Is it easier to flash using the exe or the hdr or does the exe use the hdr?
