BM-ide & I430VX
Hi,
thanks for all the replys, I am going to replace that drive.
But there are a couple of other things I wondered about:
* When the kernel loads and detects the triton chipset, during partition
check there is an error about set_multmode failing.
* hdparm -T gives a speed of 35 MB/s, I really can't get how since my
interface isn't supposed to know UDMA and PIO4 is supposed to do only 16
MB/s.
* what are DMA modes 0,1 & 2 ? It seems that my interface knows DMA, just
not UDMA/33 (especially since the kernel recognices my interface as
Triton I/II with BM-DMA controllers. Unter W95 I also use the BM driver,
or at least one that claims to be ...)
* my old HD (IBM-DCAA 3430) on the 2nd ide is VERY slow (only 2.5 MB/s
with hdparm -t), while it was about 5 MB/s on the 1st ide. triton.c writes
that the chipset has only one dma-pipeline for both ide and should do
proper sharing between them.
* speeds of the new Seagate drive vary a lot when measured with hdparm -t.
especially enabling multisector and 32bit SLOWED it down ! Also disabling
dma slowed it down, but that might be expectable :-)
Any comments, info etc. are very much appreciated since I really don't
understand what is going on here.
An other thing: I copied my old system to the new disk with cp -a (after
booting from a floppy-based linux). it seems to work (I had no problem
using X and to compile a kernel), but I just want to be sure that this is
the right way. I can't use dd since Linux gets more space on the new disk.
