1) BIOS
Vortex86DX is basically a SoC, it can be crossflashed to almost any BIOS written for it, provided it has the nessesary videocard chip BIOS rom.
I have succesfully cross-flashed PCM-3343 (Which has AWARD bios with no disable L1\L2 cache capability) with AMI bios from PFM-535S, which share the same Lynx EM+ GPU.
You can also swap the GPU ROM modules with AWARD BIOS 6.0 \ AMIBIOS8 proprietary tools (e.g. to replace fixed resolution LCD rom with CRT)
1) BIOS
First thing is rather obvious: as Vartex86DX is basically a SoC, it can be crossflashed to any BIOS written for it, provided it has the nessesary videocard rom in it.
I have succesfully cross-flashed PCM-3343 (Which has AWARD bios with no disable L1\L2 cache capability) with AMI bios from PFM-535S, which share the same Lynx EM+ GPU.
A big leap of faith from my part, however. And I sertanly DO NOT RECOMMEND tinkering that way. BIOS chip is internal in this thing, and in the case of failure you're practically screwed.
All boards I own have JTAG to flash the BIOS, but I've yet to recieve a programmer to try tinkering with it, but my expectations are not high.
I've got my hands on a ebox-3300 mobo and have successfully identified CPU and RAM straps on it (R5/R6; R7/R8; R9/R10; R11/R12; R13/R14 - are the pullup/pulldown resistors on the mobo, I'll post more details later).
It defaults at 933Mhz CPU and 300Mhz RAM. (This configuration requires a total of three pull-down straps, which made identifying them much easier)
It has more soldering-friendly 0602 type smd pads, so I think I'll use this motherboard to solder test switches and run benchmarks.
It does not qualify for me as a retro-rig due to the absence of an ISA(PC/104) slot, but can provide tons of useful data .
I've already begun identifying which straps are for CPU and which are for RAM. I've pulled R5/R6 high by soldering 4.7k to R5.
It turned to be STRAP-4 for RAM, which downclocked it from 300Mhz to 166Mhz, perfectly matching the datasheet.
There's also another pitfall with BIOS flash utilities.
To unlock some options, I've dumped original ebox-3300 BIOS using BIOSMP (original DMP utility) and SPIFLASH (which was in the archive with BIOS kindly provided by Mumak).
The sheer volume of the BIOS chip is 2MB (hence, the dump is also 2MB), but the BIOS image itself is 256KB.
2MB dump is uneditable in AMIBCP, so I had to manually cut empty space of the dump in hex editor for it to match.
Moreover, SPIFLASH dumped only empty space, which resulted in a 1835008KB dummy file filled with FF's.
Pushed my luck once more, now I have all the options I need.
Also, I'm somewhat disappointed in a way AMIBIOS8 has been implemented on these boards. AMIBIOS Core 8 bootblock has at least four methods of recovering main bios block: floppy\ATAPI\USB\Serial.
None of them are implemented on ICOP boards. Others have floppy recovery working, probably just because it's a default option they did not turn off when building an image.
Floppy recovery on my boards is useless, as they do not have floppy connector (some others do have a floppy implemented through external super i/o chip)
Besides, onboard sketchy floppy SPI emulation makes recovery procedure think a floppy is already present and tries to search for BIOS file in a void.
All I could do is connect external SPI and format it using SPITOOL.
But could not mount it as a floppy nor copy BIOS file to it. Probably lacking the proper driver in BIOS.
N2 - Pyrethrins constitute a class of terpene derivatives with high insecticidal activity and are mainly synthesized in the capitula of the horticulturally important plant, Tanacetum cinerariifolium. Treatment of T. cinerariifolium with methyl jasmonate (MeJA) in the field induces pyrethrin biosynthesis, but the mechanism linking MeJA with pyrethrin biosynthesis remains unclear. In this study, we explored the transcription factors involved in regulating MeJA-induced pyrethrin biosynthesis. A single spray application of MeJA to T. cinerariifolium leaves rapidly upregulated the expression of most known pyrethrin biosynthesis genes and subsequently increased the total pyrethrin content in the leaf. A continuous 2-week MeJA treatment resulted in enhanced pyrethrin content and increased trichome density. TcMYC2, a key gene in jasmonate signaling, was screened at the transcriptome after MeJA treatment. TcMYC2 positively regulated expression of the pyrethrin biosynthesis genes TcCHS, TcAOC, and TcGLIP by directly binding to E-box/G-box motifs in the promoters. The stable overexpression of TcMYC2 in T. cinerariifolium hairy roots significantly increased the expression of TcAOC and TcGLIP. Further transient overexpression and viral-induced gene-silencing experiments demonstrated that TcMYC2 positively promoted pyrethrin biosynthesis. Collectively, the results reveal a novel molecular mechanism for MeJA-induced pyrethrin biosynthesis in T. cinerariifolium involving TcMYC2.
