After booting from CD-ROM and going through various options - normal, text, expert - I get to the screen where the installation should start and the install just sits there -- waited at least 45 minutes. This is a new system and has a Pentium 4. Intel knowledge base says RedHat 7.0 should just work. I have a motherboard IDE/ATA-100 controller which the CR-ROM is on (as well and an IDE disk) and an Adaptec 2940UW SCSI with two SCSI disks that I plan to install Linux on. The system works fine under Windows/ME and it can see all the above hardware with no problem. The system has 256 Mb of memory so that is no an issue. I have tried booting off the floppy as well as copying the install tree to the hard disk and installing it from there. A console does come up on the Alt-F2 screen and I get messages on the Alt-F3 and Alt-F4 screens. The only complaint/error I see there is about unidentified USB devices ( an APC UPS box is connected to the USB) and the NVIDIA graphics board - which it seems to use ok as an SVGA device. The mouse and keyboard are PS/2.
I doubt the ATA-100 chipset is supported. Try putting your CDROM on a non ATA-100 IDE port and see if it works.
