What I've found to work is to add seperate sections for each adapter, basically just appending their txtsetup.oem files together. I do change the "disk" idenitfier though. For example: [Disks] d1 = "LSI Logic PCI Fusion-MPT Miniport Driver", \symmpi.sys, \ [Defaults] scsi = SYMMPI_32 [scsi] SYMMPI_32 = "LSI Logic PCI Fusion-MPT Driver (XP 32-bit)",symmpi [HardwareIds.scsi.SYMMPI_32] id = "PCI\VEN_1000&DEV_0622", "symmpi" ;etc... [Files.scsi.SYMMPI_32] driver = d1,symmpi.sys,SYMMPI inf = d1,symmpi.inf inf = d1,lsipseud.inf catalog = d1,mpixp32.cat [Config.SYMMPI] value = Parameters\PnpInterface,5,REG_DWORD,1 ;next txtsetup.oem, with d2 for the disk id [Disks] d2 = "Adaptec Ultra320 Family Manager Set - Microsoft Disk", \AdpU320.sys, \ [Defaults] scsi = a79xxNTIA32 [scsi] a79xxNTIA32 = "Adaptec Ultra320 SCSI Cards (Win XP/Server 2003 IA-32)" [Files.scsi.a79xxNTIA32] driver = d2, adpu320.sys, adpu320 inf = d2, adpu320.inf catalog = d2, adpu320.cat [Config.adpu320] value = "", tag, REG_DWORD, 20 [HardwareIds.scsi.a79xxNTIA32] id = "PCI\VEN_9005&DEV_801D", "adpu320" id = "PCI\VEN_9005&DEV_801E", "adpu320" ;etc..
