Dell PowerEdge 1950 Win9x Pata/Sata drivers / settings for making DMA working Intel 631xESB/6321ESB + 631xESB/6321ESB

[ruthan]

Hi,
i managed to install Windows 98 on Dell PowerEdge 1950 - its intel Greencreek 5000 chipset converted to retro gaming ring, i have Win2000+ OSes already working.

 But i have problem to make SATA and PATA working with DMA, for some reason its not such slow as normal not DMA machine, im using Sata for System disk and PATA is for CD-ROM.

  I controllers is Device manager working - for these MS drivers or Rloew Sata / Pata drivers both works, i even tried PurgeHD utility from Rloew, which in for some reason todays Rloew tools collections (i added it into zip bellow with some older ATA driver and SCANHDC utility - i bought it back in the day), but there is problem with channels.. They have Exclamation marks. - there are Code 10 and Code 9. AHCIBIOS ulity does not found AHCI.. in bios is just ATA for sata port.
  I think that source of the problem is that, machine as very specific setup, just 1 Sata port and 1 pata channel.. and these probably supposed to work with multiple devices on one channel, or multiple channels etc.. Maybe someone know how to fix it.
   Controllers are from Intel -drivers are for Windows 2000+

Here are HWinfo, Astra and AIDA reports from Win98 on this machine + screenshots from all Device manager Storage controllers.

I have tried to restore Windows 98 quick install image from the other machines on this HW too, there was the same problem with disk controller, but there seems to a bit more ATA / Sata drivers, there some drivers for switchable and fixed channels and whe i tried to point to driver, i got hudge list of possible drivers and wasnt sure which to use.. So far i not managed to export that more ATA/Sata drivers package form QuickInstall distro, maybe someone already did it..
   I have tried multiple Windows 98 drivers packs, but nothing compatible was found.

Its reported as:
1) Device Description  Intel 631xESB/6321ESB - PATA Controller
Device ID  8086-269E
Subsystem ID  1028-01B3

2 ) Intel 631xESB/6321ESB - SATA Controller
Device ID  8086-2680
Subsystem ID  1028-01B3

  So far i found Intel 6300ESB Sata and 6300 PATA  and later 631xESB/6321ESB drivers for Windows 98, but they seems to be just empty INF - device description change "drivers" behave the same ways and all others, at least its bootings..
