Hello, I've buy two HD Maxtor 40gb 7200rpm ata/133 (both have partition and formated), my motherboard is a Asus a7v133 with raid for ide (Promise Fast Track 100 "lite" with latest bios version 1.31).

When I start my computer, the Promise bios works fine, show the informations about my two HD and set on performance. After that, I boot with the win98 boot disk, I only have c: and it's only 39 000mb instead of 78 000mb??? But I can install windows98se but I wanna have my raid working!!!

If you need more information, just have to ask, thank you so much!!!

I've forgot to says that my bios is set to boot on raid, my jumper ATA/RAID is on RAID and both HD are master on each IDE slot.

Thank you again!!!

It sounds like you need to go into the BIOS for the raid controller (as opposed to the main BIOS) and setup the array, it has probably defaulted to a mirror as opposed to a stripe. if you delete the existing array and create a new stripe array all should be ok.

Obz comment will fix it for sure.

Read the documentation that come with your mobo for exact instructions on how to change your RAID configuration.
From what you've said in your post, it's either:
 RAID Type: Concatenation - or
 RAID Type: Striping (RAID-0)

A great site I recommend looking at is:

You must do your fdisk while your in raid, and format too, but never forget to reboot between both. Also you have to make only one partition and change it after because fdisk doesn't calcul well the space after 64gb |!!!!!!!|
