>Description:
I've trying to install FreeBSD 6.x,7.x,8.x on old server with following configuration:
* Chassis SR2200 2U 2 x 350W
* MB Intel SCB2 ATA-100 Serverworks ServerSet III HE-SL 6*SDRAM int. ATI Rage XL 8MB 2*PCI64/66 (risers)
* CPU 2 x Pentium III 1266MHz (CPUID 6B1)
* RAM 1GB (2x512MB PC133 SDRAM)
* HDD 1 x 120GB IDE
* LAN 2 x Intel 82550PM 10/100
* CD/DVD CD-ROM SAMSUNG SN-124
* Controllers Promise PDC 20267 ATA-100 Dual Channel (onboard)
It fails to boot (whether I choose default or acpi disabled at boot loader) with error BTX halted. In default mode it complains about missing acpi.ko file.

At the same time when I network boot thin client based on 7.2 i386 it runs perfectly.

Any ideas?
