[Soekris] 5501 reboot problem

[Martin Johnson]

I'm testing a 5501 with a Hitachi E7K100 IDE laptop drive, connected  
using the cable from a 4801 and temporary (cardboard) mounting  
hardware.    I'm not using  USB, CF, PCI or Mini-PCI cards.

I've installed FreeBSD 6.2-RELEASE via TFTP and FTP using the  
excellent notes at http://www.ultradesic.com.  I then csup'ed to  
RELENG_6.2 and successfully ran a 'make world' in approx 6 hours.   
All smooth and quiet.

Only problem seen so far is that the net5501 cannot see the hard disk  
after a reboot.  That is, you need to hit the reset switch or power- 
cycle the unit in order to be able to boot from the hard disk.   
Otherwise, the machine reboots but the BIOS does not see the hard  
disk. Is this a known issue?

PSU is a 12 Volt 1.2 Amp unit from an old Ethernet switch.

The boot-up messages and BIos SHOW parameters are as follows. (NB the  
line "Pri Mas  HTE721010G9AT00                 LBA Xlt 1024-255-63   
97 Gbyte" does not appear after a reboot.)

Thanks for any pointers!

- Martin.
