Pretty happy. Last year I bought a case to use for a 486 build I had gathered up parts for but to get a case I ended up with most of another 486 machine that wasn't functional. I couldn't find out the exact manufacture of this board but it is identical to the 486 vla models I have seen from multiple …

Well Solved this is definately something to do with the compact flash card or adapter. I just used a sata to ide drive adapter with 120Gb ssd and windows 98 is happy with it. Scan disk had nothing to report when it opened for setup so guess if I want decent storage it's ssd and ide adapter. which …

Ya think I give up on the compact flash seeing lots of people having issues with them. Just trying to find a decent solution. My SD to ide 8gbcards work fine but the write speeds are brutal even for this board not having dma.

definately not working even though fdisk sees proper size when scandisk runs a full scan it shows bad sectors after I would say the 8gb mark of the drive. I'm sure xtide or a drive overlay would fix this but I thought jan's modded bios would too.
