>Environment:
BTX crashes during installation, no uname -a available
>Description:
Test system:
DVD-ROM/DVD-R on ICH5 IDE, Secondary Master/Slave
2x PATA HD with SATA converter on Silicon Image 3112A (on motherboard)
2x PATA HD with SATA converter on Promise 20735 card (in PCI slot)

In my quest to get Serial ATA working with FreeBSD (mainly because I'm sick of regular IDE ribbons and rounded cables), I'm trying the Promise SATA card that came with a Maxtor drive I previously bought.

With no drives connected to the card, BTX works fine.

If I connect one or more drives to the card (using PATA to SATA converters), BTX crashes:
NTX loader 1.00  BTX version is 1.01
Console: internal video/keyboard
BIOS CD is cd0
BIOS drive A: is disk0

BTX halted

Hardware is not an issue, since the card works under Fedora Core 2 Test 1, running Linux kernel 2.6.1.
>How-To-Repeat:
Connect PATA drive with SATA converter to Promise 20375 card and boot FreeBSD 5.2 or 5.2.1 installation CD.  BTX panics.
>Fix:
No known fix.
