This is a really stupid question, and I'm vaguely embarrassed
at asking it, but here goes anyway :

I've just replaced my IDE cables with ATA100 compliant ones
(up from ATA33).

Is it possible to install them backwards and have the drives
still work ?

This is the relevant output from my dmesg :

atapci0: <VIA 82C686 ATA66 controller> port 0xffa0-0xffaf at device 7.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
ata0-master: DMA limited to UDMA33, non-ATA66 compliant cable
ad0: 39266MB <IC35L040AVER07-0> [79780/16/63] at ata0-master UDMA33
ad2: 19541MB <Maxtor 92041U4> [39703/16/63] at ata1-master UDMA66
acd0: CDROM <TOSHIBA CD-ROM XM-6202B> at ata0-slave using PIO4
acd1: CD-RW <CREATIVE CD-RW RW1210E> at ata1-slave using PIO4

As you can see, the second drive is working ok, but there's a nasty
hang after atapci0 is detected and the drive is still at UDMA33, so
I've obviously done something wrong.

Thanks,

Ceri
