CD-ROM reading error in Ubuntu 8.04 LTS installation on ServerWorks board

[John Mok]

Hi,

I tried to install 8.04 LTS server on Tyan S2518 motherboard :-

- ServerWorks ServerSet III LE chipset
- Dual PIII CPU 1.26 GHz
- 3 GB RAM
- IDE CD-ROM

The installation continued without problems, until the steps of reading 
installer components from CD-ROM. The installation stopped and  prompted 
an error of "failing to read from CD-ROM....". I tried the options to 
disable ACPI and the problem remained the same.

The installation process of 6.02.2 LTS server on the same server 
completed without any problem. Can anyone advise what went wrong and how 
I can install 8.04 LTS server successfully?

Thank you,   John Mok
