Can you try replacing the IDE cable or try a different disk?
Adrian
Yes, I’ll try hardware combos. This is basically an attempt to get a PCI ATA card working end to end, from Openboot to OS, without touching the original IDE. I have this card working with openbsd and the Openboot instructions I posted a few years back but I could not get the drives seen by Debian 9 installer, was hoping to get further this time, which I have. I’ll post back if I have more details. Thanks for the help. -Mike
Sadly no good outcome. Different cables made no difference, I tried a PDC20269 Card (which uses pata_pdc2027x) and in that case I can not see the disk nor the cdrom once the kernel has loaded. (Which is consistent with Debian 9 SILO installer on that card) That is I can boot the cd and then when it comes to the stage of loading from the media it can not be found. asmod shows the pdc2027x drive is loaded and lspci shows the card but no devices are on it. The PDC20267 (Promise ATA 100 using pata_pdc202xx_old) is the original card I was working with today and it can’t make the filesystem. [Opps posted] I went ahead and tried OpenBSD6.7 on this new disk to see if it works and it does. So I’m right back where I was before I began this exercise. I need to find a HighPoint HPT366 the non-raid kind of card to see if it can been used. I know I tried at least one SILxxx and it was not useable by OpenBoot. I’ll keep thinking about ways around this. I wonder if the FCode linking I do to the card somehow limits the DMA mode to match the onboard limit. It’s kind of a blackbox to me. But I thought once the kernels take over they would sort it out.
