Here's a strange one...
I have an old P3 machine that dual-boots Win2000 & Fedora Core 3. I intend to replace Fedora with Ubuntu sometime soon.
All has been working fine until this morning, when I added a second CD-ROM drive. Now it has problems booting.
Hardware before the change :
P3-677MHz
512Mb memory
IDE Primary Master - 4Gb Seagate HDD
IDE Primary Slave - 10Gb Samsung HDD
IDE Secondary Master - Samsung CD-RW
The change I made was to make the Samsung CD-RW into the Secondary Slave, and add a Panasonic CD-ROM as Secondary Master.
When I boot the machine, it detects all the hardware fine, but then just hangs with a blank screen (apart from the cursor in the top left corner).
If I hit F12 during the POST phase to bring up the boot menu, that comes up but it still hangs when I select boot from Hard Disk.
HOWEVER, if I boot with the Ubuntu live CD in the CD-ROM drive, it boots into Ubuntu fine.
If I boot with the Ubuntu live CD in the CD-ROM drive and hit F12 during the POST, then select Boot from Hard Disk when the boot menu appears, Grub starts up & gives me the correct choices (Win2k or Fedora), and either will boot fine.
I vaguely recall reading something ages ago about boot problems on some mobos/bioses if all 4 IDE devices were present, but I can't find any reference to this now.
Anyone got any ideas/suggestions ?
Many thanks,
Nigel.
