As for DOS usage I don't really know if the integrated northbridge of the Transmeta Crusoe are capable to do DDMA. Can you give us the full output from PCI.EXE to see which PCI IDs it uses?
Hi !
I did modify to test severval versions of setupds.exe program, version 3.16, to match the PCI ID of the ISA bridge (Intel) or the northbridge (Transmeta).
I followed this thread :
Yamaha YMF7x4 Guide
and this post:
"Modified the SETUPDS utility so I'm now able to use DDMA mode on a VIA KT133E/686B platform. Used the version on Yamaha's site and modified offset AEC0 and AEC1 from 96 05 to 86 06 (the PCI ID of the "PCI-to-ISA bridge").
Nice guide BTW. 😀"
With these values :
Bus 0 (PCI), Device Number 0, Device Function 0
Vendor 1279h Transmeta Corp
Device 0395h LongRun Northbridge
Command 0006h (Memory Access, BusMaster)
Status 2200h (Received Master Abort, Medium Timing)
Revision 00h, Header Type 80h, Bus Latency Timer 00h
Self test 00h (Self test not supported)
PCI Class Bridge, type PCI to HOST
Subsystem ID 02951279h Unknown
Subsystem Vendor 1279h Transmeta Corp
Address 0 is a Memory Address (0-4GiB) : FC100000h
Bus 0 (PCI), Device Number 7, Device Function 0
Vendor 8086h Intel Corporation
Device 7110h 82371EB/MB PIIX4E/M ISA Bridge
Command 000Fh (I/O Access, Memory Access, BusMaster, Special Cycles)
Status 0280h (Supports Back-To-Back Trans., Medium Timing)
Revision 02h, Header Type 80h, Bus Latency Timer 00h
Self test 00h (Self test not supported)
PCI Class Bridge, type PCI to ISA
But nothing changed, nothing worked as expected 🙁 any clues ?
