All I did was download the latest driver packs from the download page in 7zip format. I extracted them and then ran DPINST accross it with seaching sub folders and in legacy mode to install unsigned drivers. All drivers install accross the eight different computer types we have except for this one video card.
I don't want to toot my own horn, but I write drivers for a living and I know a few things about them. Anyway the INF file I attached contains the following section.
"128MB ATI Radeon X1300" = ati2mtag_RV515, PCI\VEN_1002&DEV_7187&SUBSYS_04021028
"128MB ATI Radeon X1300 Secondary" = ati2mtag_RV515, PCI\VEN_1002&DEV_71A7&SUBSYS_04031028
"256MB ATI Radeon X1300PRO" = ati2mtag_RV515, PCI\VEN_1002&DEV_7183&SUBSYS_0D021028
"256MB ATI Radeon X1300PRO Secondary" = ati2mtag_RV515, PCI\VEN_1002&DEV_71A3&SUBSYS_0D031028
I downloaded and extracted the the following files DP_Graphics_A_wnt5_x86-32_1005.7z, DP_Graphics_B_wnt5_x86-32_1005.7z and DP_Graphics_C_wnt5_x86-32_1005.7z. I then performed a grep looking for VEN_1002&DEV_71A3&SUBSYS_0D031028 and I did not find this in any file.
The actual Hardware ID I am looking for is PCI\VEN_1002&DEV_7183&SUBSYS_0D021028 which is the third one in My INF file obtained from Dell.
I then looked at two files with the dirver packs: \D\G\A\CX_76825.INF and \D\G\A\CX_95952.INF. Both INF files had entries for VEN_1002&DEV_7183 and SUBSYS_0D021028 but not VEN_1002&DEV_7183&SUBSYS_0D021028.
On line 945 of CX_76825.INF and on line 430 of CX_95952.INF it lists VEN_1002&DEV_7183 and its remarked. If it wasn't remarked it would work and install the driver correctly as all the files seem to be there.
Its seems to be just a matter of adding the correct line to the INF or removing the remark.
