Apple and Edge withdrew from the Blackhat conference in Las Vegas yesterday.

Shocked

Any news from the FASM team?

Question

Motherboard arrived safely? Presentation was satisfactory? We are keen to learn of your progress, and hope for same. No news in the conventional media about UEFI

Thanks for all the words of encouragement guys!

vid and I arrived Las Vegas yesterday morning safe and sound. I wish I could say the same of our demo machine ( a core 2 duo tower). When we retrieved the box from the nationally known shipper, it was obvious it had been dropped from quite a height. When we opened it we noticed that the heatsink and fan were off axis. When we powered, or rather when we tried to power it, nothing .... completely dead.

We quickly ordered another motherboard and processor for overnight delivery to our hotel. The new motherboard and processor arrives tomorrow. As our presentation isn't until Thursday, we'll have time to get the demo back on track.

We picked up our presenter credentials today and are heading to a speaker's reception in a few hours. We plan on attending quite a few of the technical sessions tomorrow and then on Thursday we're going to give ours. We've included FASM in the resources section of our briefing and will point the attendees to our favorite assembler. As vid mentioned in an earlier post in this thread, we've got the UEFI hypervisor working and we think it will make a compelling presentation.

During the lull created by the busted motherboard, we took the opportunity to take a road trip to the Grand Canyon (http://en.wikipedia.org/wiki/Grand_Canyon) late yesterday evening so we could watch the sunrise there .... pictures to come! Speaking of pictures, I've got a few good ones of vid checking into the "Speakers and VIP" registration section of Black Hat and one of him doing rude things to Venus' statue outside Caesar's Palace (venue of the Black Hat Conference). Laughing

We're putting final touches on the briefing and are all set for Thursday.

As Black Hat presenters, we get free passes for DefCon, which starts on Friday (https://www.defcon.org/). We're catching the "red eye" back to Washington, DC on Sunday night and I think that after all the stress we've sustained in getting ready for the Black Hat presentation, we'll probably let loose pretty good at DefCon.

They usually drink harder stuff than beer Razz

At FASM2007 we had some Slivovic that vid brought with him, and HyperVista had "the ceremonial bottle" filled with Jack D - I'm afraid I had a little bit too much of both, but at least I didn't "pull a vid". I did end up in the hotel lobby in my underpants, because I had forgotten where the toilet was, and that I needed my keycard to get back to my room Embarassed.

Anyway, hope the presentation goes well, guys - too bad I couldn't be there with you, but I'm sure we'll have another shot sometime. When are you coming to Denmark? Smile

That's the place where one learns what real "ol" is. (Same spelling, in Danish, as OIL, pronounced, EARL, as many people from Tennessee in USA would say, speaking of the petroleum counterpart to Tuborg.)

"øl"/"ØL", not "ol", and EARL might be relatively close, but not quite there.

Well, drink beer BEFORE the presentation Wink , and leave the hard stuff for AFTER the presentation. And hopefully, the streaking is kept to a minimum! Laughing

What exactly is a hypervisor? Question

madmatt: you live in the same state as me

windwakr: basically it's a level lower than an OS kernel, that does some amount of hardware virtualization. So, in theory, you can have a (ring0!) OS (or multiple of them) running beneath a hypervisor. For multi-OS virtualization purposes, you'll usually want some OS awareness (ie., special drivers) in order to make things go smoother/faster. But we're doing this for security, not with virtualization as the end-goal Smile

Just a a quick note to let you know that vid and I returned this morning from Las Vegas, taking the "red eye" (all night flight). I'll have a more detailed description of our Black Hat and DefCon experience including pictures later.

Although we were not able to repair the demo PC in time, the presentation went quite well. Despite competition from several other talks going on simultaneously in other rooms, our talk was fairly well attended. We received several good questions, a couple of follow-up emails from those who attended and even one fellow wishing to join our effort.

After getting the replacement motherboard and CPU at the very last minute (0730 the morning our our presentation, which was scheduled for 1000) we discovered that the power supply was also damaged and we didn't know where we could get a power supply in Las Vegas at 0730. You can get a lot of things in Vegas 24/7, but power supplies aren't high on the list in that city. Very Happy

Immediately after our presentation, we headed straight to the bar downstairs and knocked back a few.

DefCon started on Friday night and is much less formal and in some ways more technical than Black Hat. For example, they run several fun contests including a TCP/IP drinking contest where teams have to answer obscure questions about TCP/IP and if they answer incorrectly, the team has to drink shots before going on to the next round of questions.

I'll have a more detailed report of all the goings on with some nice pictures later this week after I catch up on some sleep.

Fry's electronics is a large chain, prominent in California, and Arizona, with a huge store just SW of the LasVegas Airport, a couple of miles, at most, from the Casinos. Though it would be cutting it a bit close, the store opens at 0800 (not 0730) so that a quick taxi could have delivered one of you back in the casino by 0845, with the new power supply.
Next time!!!

I had the pleasure of observing the rehearsal for this presentation, back in mid July, and at that time, the physical connection with the second unit had a small defect, in other words, I too, just like the conference participants, did not observe all of the actual interaction with UEFI, but, nevertheless HyperVista's lecture itself was so well presented, that the absence of a physical demonstration was not really essential. One imagines that the discussion could possibly have been even more substantial, at the Black Hat conference, had the demo functioned as intended, however, the disappearing act of the second computer, I am certain, dampened the participants' enthusiasm for HyperVista's contribution by not even the tiniest, immeasurable degree.

Thanks for that MazeGen, having just brought a new laptop, nothing special (P8400), which has an EFI BIOS (InsydeH20) and VMX I'm struggling to catch up with this technology.

So far I am really disappointed, this EFI BIOS appears to be a closed system and the legacy emulation seems to really suck.

For instance, just booting into DOS and running GRDB's dump command 'd 0 ffff' takes over 3 minutes (210 seconds) whereas on my old PIII it takes about 4 seconds !

Looking at a BIOS print interrupt with the following code
Code:
        mov   ax,3
        int   10h          ;reset/clear screen

        xor   ah,ah        ;
        int   1Ah          ;get tick count
        push  dx           ;and save

        mov   ax,0E41h     ;print 'A'
        mov   cx,8000h     ;this number of times
        
TestIt: int   10h          ;Print
        loop  TestIt

        xor   ah,ah        ;
        int   1Ah          ;get tick count
        pop   ax
        sub   dx,ax        ;dx = ticks taken    
Gives 6 ticks for the PIII and 270 ticks for the P8400

So the P8400, which is running over 2x faster than the PIII, takes 45 times longer !

Also using the FreeDOS pre-installed OS results in ocassional lockups.

Okay, back to the x86asm.net article
x86asm.net wrote:
THEN the VMX bit (bit [2]) can not be set and VMX is absolutely
disabled with no chance to enable it except via BIOS upgrade.
Not sure if upgrade is the right word here, it implies flashing the BIOS. In some cases that may be necessary but on the laptop I have this one of the 'very few' options that is settable in the BIOS setup and whether VMX is enabled or not, the lock bit remains set in either case. Also it seems some BIOS's that leave VT disabled with no option to enable in the setup, can be enabled by finding the relevant bit in NVRAM and setting it.

Anyway, I've got a lot to learn about this frustrating new stuff (for me), maybe too much.

Mr HP, can I have something like my old BIOS back please. Sad

There are few more words used bit wrong in that article, and I was too lazy for redaction lately...
