Setting up RAID 0 with 3 SCSI disks


Hi people :-)

I recently got an HP Netserver LH Pro machine (paid $75nzd for it)
It's got:
two Pentium Pro 200 CPUs
512 MB RAM (ECC I think, in two 256 MB modules. 2 empty slots left over!!!!!!!)
three 4.5 GB SCSI hard drives (Seagate ST34501WC, 10K I think)
SCSI CDROM
Floppy

I had a go at setting up RAID 0 in Slackware with mdadm (can't remember the exact command I gave), then:
I was able to do "cfdisk /dev/md0" and create a filesystem
I then formatted it: "mkfs.reiser /dev/md0"
All went fairly well
then "mount -t reiser /dev/md0 /mnt/array"
I could write files to /mnt/array I think, and it worked well

"hdparm -t /dev/md0" gave faster results than /dev/sda (the disk without raid)

The SCSI (or raid or whatever) controller is Adaptec AIC-7880P


Question 1
How do I know whether I have hardware or software RAID?????

Question 2
How would I get LILO to boot off a RAID array?
Would I change "root=/dev/sda" to "root=/dev/md0", or would that cause a disaster?
How would I install Slackware onto an array?

Cheers
Forrest

PS do U reckon it was a good buy?
