This board functions perfectly under Linux 2.4.19-pre6, Linux 2.5.8-dj1, Windows XP Professional and will boot up and reboot off of both FreeBSD 4.5 and 5.0-DP1 cds. Under Linux the board will boot up, never crash, and shutdown, everything except for rebooting works. Windows and FreeBSD both have no problems rebooting. If I try and reboot using Linux 2.4.19-pre6, 2.5.8-dj1, the RedHat 7.2.93 CD, the RedHat 7.2 CD or the Gentoo Linux 1.0 CD it always behaves exactly the same: init runs it's shutdown sequence and then the words "Please stand by while rebooting the system..." appear shortly followed by the words "Rebooting system." at this point the screen does not clear and wait for the BIOS to reinitialize the video as Linux does with other boards and Windows and FreeBSD do with this board, instead the text stays there for at least 15-20 seconds (maybe longer) then when it finally blanks the video and the monitor light begins to flash it goes straight into the Adaptec SCSISelect scan (I can tell because my HD light comes on and the CDROMs I have are accessed in order), immediately after the SCSISelect scan the video stays off and instead of giving a successful BIOS beep (one tone) and booting GRUB it gives a very weird sequence of tones and then the box is permanently hung until I power it off and on again or until I hit the hard reset switch on the front. Again, this only occurs while rebooting linux and does not happen while shutting down Linux (which works perfectly) or while shutting down/rebooting other OSes. Also, I have tried the following combinations of Linux command line reboot variants: reboot=bios, reboot=smp, reboot=hard, reboot=bios,cold, reboot=hard,cold, reboot=bios,smp. All of the previous entries behave exactly the same, and they all behave the same across multiple BIOS versions (though maybe a different BIOS would work). I also used the reboot=bios patch posted earlier today in my testing of rebooting 2.5.8-dj1. Does anyone have any ideas about what might be happening to the reboot sequence Linux tries to use or how to fix it for this board? It uses 512 MB of Kingston Registered ECC PC2100 DDR SDRAM, a 450 Watt Enhance Power Supply, and dual AMD Athlon MP 1900+ chips. Thanks for any help.
