Dear All
I am trying to install my os as :

ok>boot cdrom - install

but receiving the following :

"IDprom checksum error
getexecname() failed
/sbin/rcS /etc/vfstab cannot create
INIT:failed write utmpx enrty
INIT:single user mode
INIT:execle of /etc/sulogin failed
Enter run level"

Can you please let me know what is wrong here?
Thank you in advance

hi,
did you try another alternative cmds in obp

boot cdrom

boot cdrom -s

boot cdrom -s - install

This looks more like a hardware error. But for sure you don't need the extension - install if you are booting from cdrom. That extension is only used, if you install from a jumpstart server to do an unattended installation.

What kind of hardware are you using?

I am using NatureTech 747s Laptop as my hardware.

hmmm your hardware is seem old ( Sun Workstation ) ?
maybe you should to replace or reprogramming ( if it possible ) your Nvram chip.

Hi hadimotamedi,

i m not sure where is the NVRAM chip part number writes in another than motherboard..
i cannt find the any related nvram part no information about your system.

maybe ( if there is ) u can check the product/system documents ( like invoice , manuals , sys dump docs .. ) that came with the your powerbook computer.

but of course the most guarantee way to look on the the motherboard.
because you already will have to open the powerbook shelf/case when you buy a new nvram chip :slight_smile:

otherwise i can only walk the idea from your system's cpu arct.
your system has ( Ultra SPARC IIe/IIi ) ? is it correct ?
if it is ok , i just can guess this compatible nvram chips for your system.

so it is maybe "525-1417, M48T59-70PC1" chip ?
i use this reference site.
IDPROM - Parts

if it is this , then you can find the related products..
for exa :
525-1417, M48T59-70PC1, Sun NVRAM for Ultra 2 (M48T59-70PC1), Sun Microsystems Products
525-1417 IDPROM (NVRAM) For Sun Ultra 2 Workstation New Battery 1 Year Warranty | eBay

if you can be sure somehowly , you can find more alternative shopping sites with different prices..

good lucks
