Warp 4 (Merlin) on 755CD - conflict between cdrom and pcmcia

[g_prosser@cix.compulink.co.uk (Gerry Prosser)]

Just got round to installing Merlin on my TP755CD. 

So long as the diskette drive in place, rather that the cdrom drive, the 
pcmcia ethernet card is recognised and works well. 

But when I reboot with the cdrom in place, the pcmcia card is disabled 
with the following message during the boot sequence::
"ifconfig:ioctl (SIOCDIFADDR) no such interface"

There are no obvious clashes on irq, dma or memory allocation. ..... any 
ideas as to what might be going on here ?
