[AuckLUG] CAN'T GET A SCREEN IMAGE IN EDUBUNTU

[Alan]

 I have successfully downloaded and burnt the ISOs for Kubuntu(for myself) and 
Edubuntu(for my grandsons).
 
 When I install Edubuntu I get a message:
 
 ACPI: Unable to locate RSDP
 
 then I get the preliminary Edubuntu Splash screen shortly followed by a blank 
screen. I can hear the CD drive working but eventually I get a message:
 
 Attention
 Out of Range
 H 255Khz V66.1Hz
 
 I have tried loading Kubuntu on the same machine and, while I get the same 
ACPI message, Kubuntu appears to load correctly and there is no problem with 
viewing information on screen.
 
 I took Edubuntu 6.10 CD to work and ran it on my PC there and it loaded fine 
so I guess it is down to a combination of Edubuntu and my monitor/PC. Tried a 
different monitor on my home PC and this time I got the "Black Screen of 
Death" - can't see anything...not even the Out of Range message.
 
 The monitor is an IBM 50/60hz E74 CRT and the PC a Compaq P2/266 with on 
board video (no card).
 
 I gather that I need to change the monitor settings (that should be a laugh 
with my experience but I can try anyway)but I can't do anything with a blank 
screen!
 
 How do I get to see something (is there a "Safe Mode or something that I can 
use)and when I do how do I change monitor settings when I get there.
