591	Boot stops at RESOURCE.SYS followed by 'A disk-read error occurred'	ataylor		"Gigabyte GA-A75M-DS2 micro-ATX motherboard.  The system works with OS2APIC.PSD installed.  Kernel 14.106_SMP, 2GB RAM.

With ACPI.PSD installed, the system will not boot.  Deleting OS2LOGO shows that the system attempts to load RESOURCE.SYS, waits for a long time, then eventually shows the message ""A disk-read error occurred.""  A hard reset or power-off is then required.

Have tried with no switches, with /VW, and with /PIC, all with the same result.  

Have tried 3.21.07, 3.22.02 and the 3.22.03 test build from ticket #590.

The I/O controller behaves very oddly with respect to OS/2 on this board.  It is NOT set to AHCI mode in the BIOS, but rather to 'native IDE' mode; however, even using OS2APIC.PSD, the system will not successfully locate the hard disks unless OS2AHCI.ADD is loaded in CONFIG.SYS alongside DANIS506.ADD.  Even more strangely, it won't even locate a USB-attached CD-ROM drive unless OS2AHCI.ADD is loaded.

(This system has no serial port.)"	defect	new	minor	Release 4.00	ACPI PSD	3.22.02
