FreeBSD kernel questions
I'm trying to make a kernel for FreeBSD 5.3 on this system:
PART NAME AMOUNT
Case 4U22ATX550EPS-EC 1
Side Rails Antec 26" Side Rails 1
Mainboard Tyan 5350G2NR 1
Memory DDR-RAM DIMM 512MB Kingston ValueRAM 8
Processor Xeon 2,8GHz, MPGA, 1 MB, 800 FSB 2
CD-ROM Asus CD-S520 Atapi 52x 1
HDD for OS HD AT 120GB Western Digital WD1200BB 1
HDD for RAID HD AT 160GB Hitachi Deskstar 7K250 SATA 2
But I'm not sure which RAID controller the mainboard uses and couldn't fin this in the documentation on Tyan's website.
Here is what the kernel looks like:

I'm also not too sure about these:

device atkbd0 at atkbdc? irq 1 flags 0x1
device psm0 at atkbdc? irq 12
device vga0 at isa?
device npx0 at nexus? port IO_NPX irq 13
device sio0 at isa? port IO_COM1 flags 0x10 irq 4
device sio1 at isa? port IO_COM2 irq 3
I actually got the kernel from an example on the internet and started customizing it with the manual, but it doesn't say anything about the "at...", what is this for? Should I leave it like this or stick to the manual?
Does anyone know if there is anything I can filter out for extra performance or if I've made any mistakes? Because it's my first custom kernel, and I'd like to be sure it'll work.
BTW: Are COM ports needed for anything else than the stuff connected through it?
Thanks,
Ken
