Yeah, I went through the same thing last fall when i was building my answer file. Its worth while adjusting the BIOS on your test machine. I must have installed Win7 50 times on that machine. It would have been a huge bummer to have to hit a key to boot from the Win7 CD each time. But once i had an answer file, I just trusted my timing. And as I said in another message, a light probe can come in handy too. ----- Original Message ----- From: "Alex Coleman" <AlexC@davis-express.com> To: "Blind sysadmins list" <blind-sysadmins@lists.hodgsonfamily.org> Sent: Tuesday, August 28, 2012 4:15 PM Subject: Re: [Blind-sysadmins] Working in System BIOS
John, I've got the answer file built and was looking for a way to make sure I could boot from CD in the bios. I ended up having someone look at it. I just have to press the spacebar at just the right time to invoke it.

When you say you're trying to set up an unattended install, do you mean you're still working on the answer file? The reason I ask is because I think it matters whether you want to modify the boot sequence on one machine or twenty.
I did about twenty installs on Dell workstations this summer and I just memorized the sequence of keys to press to boot from my device. You may need sighted assistance to get started or yu may be able to get it by experimenting. Most likely, pressing F12 during boot will bring up a list of bootable devices. If you have a light probe, that can help you tell if that menu has appeared. I would find the highlighted item with my light probe. It would be beeping and when I pressed the down arrow, I would know it moved to the next item. Then I could find the next item by moving the light probe down a little. If that didn't work, I'd know I wasn't in the boot device menu.
I also have one of those PC Weasel cards someone else mentioned. The good news is that they work really well in Dell workstations. Some BIOS setup programs don't test for whether the VGA card can go into graphics mode. But Dell's BIOS always have. So it dropps back into character mode and the PC Weasel works. The bad news is that these card haven't been manufactured for about 5 years and they are getting to be very difficult to find. They work by looking like a VGA card to the system but putting out characters on a serial port on the card. You connect a null-modem cable and get the output in a terminal emulator on another PC.
But I don't think the PC Weasel or the OCR approach is practical for a large number of installs. Better to try to memorize the key sequence.
One other note just for future reference... There is a linux command to change the boot sequence. Its "ipmitool chassis bootdev <device>". Of course, this requires you to already have linux installed and to have ipmi working, which in itself is no small task. Well, its fairly easy on Dell servers and I already wrote a entry on it for the IAVIT wiki. There is also the Dell Remote Access Card (DRAC) that can be ordered as an add-on for Dell servers. But I don't know if any of this can help you.

Thanks for any pointers or help that you can provide.
