On a 486 DX2-80 with 16MB running NT Server SP4 I have a Hard Disc and a CD-ROM on the same IDE channel. The BIOS does not support 2 IDE channels. ATAPI will not start because of a conflict with ATDISK. Both "claimed an IO port range with starting address 0x28 and 0x2c, and length in data address 0x30."
I saw a reference somewhere that this would be fixed in SP4 but apparently hasn't, or I'm doing something wrong.
Is it possible to to get this configuration to work?
