Hi,

I am seeking a powerfull mainboard for Pentium 4 or Xeon. But problem is
with eide busmastering with chipsets: with southbridge - Intel ICH4, SiS
963 (These we have tested). When will QNX support them? And is eide
busmastering supported on Intel E7501 (ICH3-S)?

Thanks

We are currently adding support for the new chips.

And is eide busmastering supported on Intel E7501 (ICH3-S)?

The eide driver supports some of the ICH3’s. It depends on the device id.
Here is a list of the supported chips:

Manfacturer Chip Vendor Id Device Id Revision Xfer Mode
Intel 82371FB 0x8086 0x1230 BIOS
Intel 82371SB 0x8086 0x7010 MDMA 2
Intel 82371AB 0x8086 0x7111 UDMA 2
Intel 82801AA 0x8086 0x2411 UDMA 4
Intel 82801AB 0x8086 0x2421 UDMA 4
Intel 82801BAM 0x8086 0x244A UDMA 5
Intel 82801BA 0x8086 0x244B UDMA 5
Intel 82801CA 0x8086 0x248B UDMA 5
Intel 82801CAM 0x8086 0x248A UDMA 5
Intel 82801DB 0x8086 0x24CB UDMA 5

Intel 82801DB is ICH4 and works slowly. Tested under QNX 6.2.1.
Motherboard MS-6704 Ver:1 (845PE Max2), IDE Bus master enabled in BIOS.
