Hi Bâshrat! Thanks for your work! I have some questions to you. Do you use standart windows drivers (from driver.cab) in your massstorage DP? Does your pack overrides standart windows drivers during 1st stage of text-mode Setup? I'm asking you this question because I have a BSOD (0x0000007B) with Ali ide (not raid). If I use my Windows Installation disk without integrating your massstorage drivers everything is OK. I'm using latest DP BASE V5.03.2 and DP MassStorage V5.03. I've compared original win xp sp2 TXTSETUP.SIF and yours: -original aliide.sys = 1,,,,,,3_,4,1,,,1,4 -yours aliide.sys = 1,,,,,,4_,4,1,,,1,4 Maybe I can just replace 4 with 3 and everything will be ok? Sorry, I have no ability to test it, because that pc with Ali chipset is far from me now.
