cdrom not recognized when attempting to install from floppy using SmartBootManager

[Graeme Jones]

I am trying to install Ubuntu Linux on an older Pentium machine.  I created
a boot floppy using SmartBootManager, and burned the Ubuntu CD-ROM boot CD.

When I boot from the floppy, the CD-ROM drive does not show up in the list
of drives available to boot from.  So I did a bit of reading and discovered
that the problem may be non-standard I/O port addresses for my CD-ROM.  I
wasn't sure how to find out what those addresses are, so I installed Windows
2000 (grrr) and ran the System Information program, which reports al the I/O
addresses as follows:

Address Range Device Status
0x0220-0x022F Sound Blaster 16 or AWE32 or compatible (WDM) OK
0x0330-0x0331 Sound Blaster 16 or AWE32 or compatible (WDM) OK

0x00F0-0x00F0 Numeric data processor OK

I am fairly certain that the CD-ROM is on the Secondary IDE channel, so I
specified 170,177 as the I/O port addresses for the CD-ROM in
SmartBootManager, saved the settings and then rebooted... still does not
recognize the CD-ROM.

One question is what exactly are the two addresses that are supposed to be
entered in the CD-ROM I/O port settings?  Assuming the CD-ROM is on the
Secondary IDE channel above, are 170, 177 the right numbers to enter?

Any help would be greatly appreciated.  I am a Linux neophyte, and Ubuntu
seems really cool.  Would like to make it work on my old Pentium.
