Thanks for the suggestion! I didn't know about /boot/config*. A lot
of things in my kernel was compiled in as "m", and I made them "y"
like Knoppix. There were some things set to "y" in Knoppix that I
couldn't set to more than "m" in make xconfig; probably I'd have to
enable experimental code ot that one option three screens back that
enables 12 different parameters scattered all over. Anyway, I changed
these (not necessarily contiguous):
# ATA/IDE/MFM/RLL support
#
CONFIG_IDE=y
# IDE, ATA and ATAPI Block devices
#
CONFIG_BLK_DEV_IDE=y
CONFIG_BLK_DEV_IDEDISK=y
CONFIG_IDEDISK_MULTI_MODE=y
CONFIG_IDEDISK_STROKE=y
CONFIG_BLK_DEV_IDECD=y
# Presumably unnecessary
CONFIG_BLK_DEV_ISAPNP=m
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_ALI15X3=y
# CONFIG_WDC_ALI15X3 is not set
It came up in DMA mode, and "hdparm -t" reports 55 MB/sec. Many
thanks, Johann!
