I do not think so. The HP DC7100 Intel 915 + 82801FB uses exactly the same BIOS naming convention. With both computer models in both Windows 98 and 2000 the "combined" mode presents OS with just one dual ATA controller with one PATA and one SATA. Both subcontrollers do show master and slave drives. It disables the third from the integrated controllers, as well.
On the other hand, the "Separate" settings prevents Windows 98 from booting, while Windows 2000 detects additional controller.
My observations are showing the same Windows 98 instalation ported to DC7100 works significantly faster with some disk related operations. In D530 i865 P4 3GHz ICH5 moving about 1GB of data by a DOS based application works several times slower, than on DC7100 i915 P4 2.8GHz ICH6 with a much slower HDD.
It could be related to a fact the ICH5 82801EB is the first from the SATA capable 82801 series, so it could have some bugs in the BIOS "IDE compatibility mode" or driver for Windows 98.
