I'm having some trouble installing 4.7 from CD on a new machine, but
I may finally be close enough to ask a meaningful question. The
hardware includes
Motherboard: ECS P4S5MG/651+, AMI BIOS, 2.4 GHz P4, 1 GB DDR RAM
Primary IDE:
Master: 40 GB Western Digital HD
Slave: 80 GB IBM HD
Secondary IDE:
Master: No-name DVD-ROM
Slave: No-name (Optirite?) CD-RW, 40x
I can boot the installation CD and things seem normal until I get
ad0: READ command timeout tag=0 serv=0 - resetting
ata0: resetting devices ..
and nothing more. I thought this was related to the ATAPI problems
discussed on the list off and on in recent months, but the el cheapo
CD and DVD drives seem to be working fine while the hard disks are
causing problems.
I've checked the jumpers carefully, swapped out the cable, tweaked
everything in the BIOS that looks remotely related, and tried each
disk alone with no change. I tried to install NetBSD 1.6 from
CD with similar results, but the error message grumbled about DMA.
Aha, said I, back to the FreeBSD archives...at length I found that
pausing the loader and entering
set hw.ata.ata_dma=0
boot
will let the installation proceed, but it looks, er, drastic.
For what it's worth, MS Windows XP Pro installs without a hitch.
Sigh.
Can anyone shed some light on this behavior or suggest a proper fix?
Cheers,
Michael
