I have 18.9G Quantum LCT20 plus 7.85Gb Quantum LCT8 and 3.99 Seagate.

The OS is on 18.9G.

I wanted 18.9 on ATA 100 Promise Primary Controller as master and the others on the ATA100 Promise Secondary Controller as 7.85Gb Master, 3.99Gb Slave.

Because of positioning, the cable connecting the secondary to the two smaller drives is not quite long enough.

It was long enough to go from Promise ATA 100 primary so I did that and connected the 18.9Gb to the Promise secondary controller.

I didn't expect the system to boot as I had always been under the impression that the primary partition had to be on the first Hdd ?

Well to my surprise it booted fine.

In post it shows HD0 = 7.85, HD1 = 3.99 and HD2 = 18.9

Fdisk and XOSL both show HD1 as 18.9, HD2 = 7.85 and HD3 = 3.99

The disks are partitioned as follows:

18.9 = Pri 1Gb, Pri 2 Gb, Pri 2Gb Ext 13.9gb split into logical drives
7.85 = Ext 7.85 split into 2 logical drives
3.99 = Ext 3.99

Should this have worked or is it because I have XOSL installed ??
