> o i845G fixes
I just tried 2.4.20-pre6 on my Intel 845GBVL board (845G chipset). For the first time DMA is available with the DVD drive, without a -ac patch. But UDMA(25) as opposed to UDMA(33) with 2.4.20pre5-ac1.Also I got some junk characters in 2.4.20pre6 when it was probing for IDE devices:
*****DMESG 2.4.20pre6 snip of the Intel board ***** Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx ICH4: IDE controller on PCI bus 00 dev f9 PCI: Device 00:1f.1 not available because of resource collisions PCI: Found IRQ 5 for device 00:1f.1 PCI: Sharing IRQ 5 with 00:1d.2 GARBAGE CHARACTERS HERE: BIOS setup was incomplete.

(Award BIOS as opposed to Intel's). DMA started to work with 2.4.20-pre5 on this board. The latest -ac patches do not work on this machine.
Here are full links to the Intel 845GBVL dmesg and lspci: http://ac.marywood.edu/tspin/www/dmesg2420pre6.txt http://ac.marywood.edu/tspin/www/dmesg2420pre5ac1.txt http://ac.marywood.edu/tspin/www/lspci2420pre6.txt
Thanks! If anyone needs more info, let me know.
