the 2.4.18-5 kernel has some i485 support; limbo will actually support i845 IDE properly will the kernels in null rebuild cleanly on a 7.3 system? Could I rebuild those kernels to get dma support on a machine with an 845e chipset? or maybe 845g? 1) yes you can rebuild them 2) no it's not a chipset thing it's a bios thing... so it doesn't too much depend on the exact chipset as it depends on the bios is it a bios issue that has been patched by some vendors? or is it not a buggy bios problem but a problem with the kernel interacting with the bios? Current errata kernels handle this. |
