Good work!
It seems that the problem disappeared in the version 7.07!
Just check the following code. It can cause some conflict! (line ms_1_hwids)

SI-3]
;This driver is only for SIS 182 RAID Controler!!!!! Please update "ms_1_hwids"!!!!
ms_count             = 1
ms_1_deviceName        = "SiS 182 RAID Controller"
ms_1_tag            = "sisraid2"
ms_1_sysFile        = "sisraid2.sys"
ms_1_hwids            = "PCI\VEN_1039&DEV_0182,PCI\VEN_1039&DEV_1182"
ms_1_isBusExtender    = false

Thanks

Post updated!

The driver was disabled on this package version (DP_MassStorage_wnt5_x86-32_7062)! The controller is not recognized in boot process!

I suggest the following modification in the .INF file:

-----------------

[SI-1]
;This driver was disabled. (ms_count = 0)
ms_count             = 1
ms_1_deviceName        = "SiS 181 RAID Controller"
ms_1_tag            = "sisraid1"
ms_1_sysFile        = "sisraid1.sys"
ms_1_hwids            = "PCI\VEN_1039&DEV_0181"
ms_1_isBusExtender    = false
   

[SI-2]
;This driver was disabled. (ms_count = 0)
ms_count             = 1
ms_1_deviceName        = "SiS 180 RAID Controller"
ms_1_tag            = "sisraid"
ms_1_sysFile        = "sisraid.sys"
ms_1_hwids            = "PCI\VEN_1039&DEV_0180"
ms_1_isBusExtender    = false
   

[SI-3]
;This driver is only for SIS 182 RAID Controler!!!!! Update "ms_1_hwids"!!!!
ms_count             = 1
ms_1_deviceName        = "SiS 182 RAID Controller"
ms_1_tag            = "sisraid2"
ms_1_sysFile        = "sisraid2.sys"
ms_1_hwids            = "PCI\VEN_1039&DEV_0182,PCI\VEN_1039&DEV_1182"
ms_1_isBusExtender    = false


[SI-4]
ms_count             = 1
ms_1_deviceName        = "SiS 1184 RAID/AHCI, 1185 AHCI"
ms_1_tag            = "sisraid4"
ms_1_sysFile        = "sisraid4.sys"
ms_1_hwids = "PCI\VEN_1039&DEV_1184,PCI\VEN_1039&DEV_1185"
ms_1_isBusExtender    = false

-----------------

Now the controller SIS 180 and 181 will be recognized!

(SIS's Drivers 180, 181 and 182 are different)

The package "DP_MassStorage_wnt5_x86-32_7064" had the same problem.
I suggest the same alteration in the .INF file.
